Researchers at the Korea Institute of Energy Research have developed a new palladium alloy composite membrane for hydrogen separation. Palladium-based membranes have been used for decades in hydrogen extraction because of their high permeability and good surface properties and because palladium, like all metals, is 100% selective for hydrogen transport. Palladium membranes have been used to provide very pure hydrogen for semiconductor manufacture, fuel cells, and laboratory use. Palladium also combines excellent hydrogen transport and discrimination properties with resistance to high temperatures, corrosion, and solvents. Further, palladium is easily formed into tubes that are easily fabricated into hydrogen extraction and palladium surfaces are not readily poisoned by carbon monoxide, steam, and hydrocarbons. This exciting technology relates to an advanced preparation method of palladium alloy composite membrane for hydrogen separation. Generally, a separation membrane used for the preparation of ultra-high pure hydrogen, has low permeability. This possesses a significant challenge to hydrogen separation. Intensive and extensive research on the improvement of the selective permeability of membranes used for hydrogen separation has been, and is presently, being carried out. The commonly used non-porous palladium membrane has high hydrogen selectivity but low permeability. Therefore, despite the selective hydrogen permeability of the separation membrane being intended to be improved by coating the surface of the porous material with a thin palladium membrane, the membrane still suffers due to frequent deformities caused by phases change of the lattice structure during hydrogen absorption. With the goal of preventing such deformations, a palladium alloy separation membrane is primarily used, at present. However, this common method of using a metal alloyed with palladium, also incur limitations. Notably the frequent palladium-copper alloy membrane suffers low hydrogen selectivity and poor adhesion, issues which commonly lead to brakes in the palladium-copper alloy separation membrane. This advanced technology has been designed to overcome the common issues experienced during the application of palladium alloyed membranes for hydrogen separation. An objective of this technology is the provision of an advantageous palladium alloy composite membrane, which requires a small amount of palladium and thus possess high hydrogen selectivity, high durability and enables improvements in properties of the separation membrane, regardless of the kind of support.

Researchers at the Korea Institute of Energy Research (KIER) have developed a method of fabricating copper indium gallium selenide (CIGS) thin film for solar cell. This innovative technology relates to a method of fabricating a copper indium gallium selenide (CIGS) thin film for solar cells through co-vacuum evaporation, and a CIGS thin film for solar cells fabricated using the same method. This advanced method enables the fabrication of CIGS thin-film using a simplified process of co-vacuum evaporation. Using this method enables an elimination of commonly experienced deterioration in the properties of thin-film crystal growth while encouraging improved band-gap gradings and sustaining reduced production costs. Solar cells are instrumental in climate change mitigation and adaption due to their capability for cheap mass production and minimal pollutant by-products. A key component in solar cell production is the use of a semiconductor material for solar energy absorption. CIGS, a semiconductor material, possess higher conversion than other thick film solar cell materials and, due to its capability to be fabricated to a thickness of 10 micros or less, can be stably operated even after long-term use. What’s more, CIGS is predicted to be a low-cost, high-efficiency solar material alternative to silicon. Solar cells can be divided into numerous types depending on the materials used in their light-absorption layer. The most commonly available solar cells are silicon solar cells, unfortunately due to the high cost of pure silicon these cells are becomingly less economically viable for mass production. Thin film type solar cells are fabricated to a thin thickness and thus require less material consumption, as well as being lightweight and having an increase in application range. A CIGS thin-film can be fabricated by vacuum deposition or non-vacuum coating. Particularly, vacuum deposition may include co-evaporation, in-line evaporation, a two-step process (precursor-reaction), and the like. Co-evaporation has traditionally been used to fabricate high-efficiency CIGS thin-film solar cells. However, co-evaporation technology is difficult to commercialisation due to the complicated nature of the process involved and the challenge of fabricating a large area solar cell. A partial solution to these issues has been the design of two-step (deposition/selenization) processes capable of facilitating mass production. However, these newly designed process often encounters drawbacks relating to scaling-up of technology and regulation of the flux of elements in each production step. Subsequently, there is a need for a simplified process of fabricating CIGS thin-film for solar cells which can achieve high crystal growth and improved band-gap grading. The technology, developed and presented by the KIER, has been conceived to solve the problems related to CIGS fabrication. This advanced technology offers a refined method of fabricating copper indium gallium selenide (CIGS) thin film for solar cells, using a streamlined co-vacuum evaporation process capable of maintaining crystal growth and band gas grading while also minimising production time and cost, as compared with conventional co-vacuum evaporation processes.

Researchers at the Korea Institute of Energy Research have developed a carbon dioxide (CO2) capture process for treating exhausts gas using a polymer membrane. Carbon sequestration requires a multi-step procedure whereby waste CO2 from large point sources, is captured, transported to storage sites and deposited. Carbon capture is a critical step in this process and represents a significant portion of the overall cost. This newly developed exhaust gas treatment system for CO2 capture offers numerous advantages over existing technology including: reduction in environmental harmful exhaust gases from carbon capture process; minimisation of installation space requirements; and a significant reduction in installation costs. In recent years there has been an accelerated development of technology focused on the reduction of CO2 emissions, due in part to the increase of climate change mitigation focused regulations. Advanced carbon capture technology is at the forefront of research centred on the reduction of CO2 emissions. Prior commercialised carbon capture technologies have neglected to incorporate methods for handling the unavoidable harmful exhaust gasses present in the carbon capture process. Consequently, there is a need for methods of managing these gasses within the carbon capture process. Researchers at the Korea Institute of Energy Research have met this challenge and designed a sophisticated polymer membrane process capable of treating the harmful exhaust gasses present during common carbon capture method. This advanced technology addresses the necessity of managing these gasses and their known negative environmental implications. This newly developed exhaust gas treatment system for carbon capture offers numerous advantages over existing technology. Specifically, harmful exhaust gasses can be removed; installation space, of the desulfurization facility, can be minimized and process costs reduced through the application of exhaust gas treatment device using the polymer separator.

Researchers at the Korea Institute of Energy Research (KIER) have developed a method of manufacturing high-density CIS thin film for solar cells. This innovative technology relates to a method of manufacturing high-density CIS thin film for solar cell and a method of manufacturing a thin film solar cell using the CIS thin film. Specifically, this technology relates to a method of manufacturing CIS thin-film by coating CIS, CIGS or CZTS nano-powders on a substrate via non-vacuum coating, followed by heat treatment with the cavities between the nano-powders being filled with elements such as copper, indium, gallium, zinc, tin, etc. Solar cells directly converting sunlight into electric energy have various merits such as avoidance of contamination, infinite resource and semi-permanent lifespan, and are thus anticipated as an energy source capable of solving the problem of energy depletion. A key component in solar cell production is the use of a semiconductor material for solar energy absorption. A CIS or GCIS thin film is a compound semiconductor which possesses a higher conversion efficiency, of about 19.9%, than other thin film solar cells and, due to its capability to be fabricated to a thickness of 10 micros or less, can be stably operated even after long-term use. What’s more, CIS or GCIS is anticipated as an inexpensive, highly efficient solar cell capable of replacing silicon. Solar cells are classified into five types depending on materials for a photo-absorption layer, and a silicon solar cell is most widely used in the art. Recently, however, a rapid increase in raw material costs due to undersupply of silicon has led to increasing interest in thin film solar cells. Thin film solar cells are manufactured to a low thickness, thereby providing merits such as low consumption of material, lightweight, wide application ranges, and the like. A GCIS solar cell is formed using a thin film having a thickness of several micrometres by vacuum deposition, or by precursor deposition in a non-vacuum state and heat treatment of the precursor-deposited thin film. Vacuum deposition is advantageous in that it provides a highly efficient absorption layer. However, vacuum deposition disadvantageously provides low uniformity and requires expensive equipment in forming a large area absorption layer, and causes a material loss of about 20% to 50%, which leads to high manufacturing costs. The inventors of the present invention carried out extensive studies to obtain a method of manufacturing a high-density CIS thin film, CIGS thin film or CZTS thin film through the non-vacuum coating. Subsequently identifying that high-density CIS thin film can be formed when heat treating the CIS thin film, CIGS thin film, CZTS thin film, with cavities of the film filled with filling elements such as copper, indium, gallium, zinc, tin, and the like. The technology, developed and presented by the KIER, has been conceived to solve the problems related to CIS fabrication for solar cells. This advanced technology offers a refined method for manufacturing high-density CIS thin film for solar cell and method of manufacturing thin film solar cell using the same, through a streamlined method which provides high-density CIS thin film while also minimising manufacturing costs and time requirements.

Researchers at the Korea Institute of Energy Research (KIER) have developed an innovative device for controlling sample temperature during photoelectric and solar cell measurement. This technology specifically relates to a device for maintaining a constant temperature of solar cell samples in a procedure for measuring photoelectric and solar cell characteristic. This advanced technology is particularly valuable in response to the increasing attention being placed on alternative next-generation clean energy sources. As such, greater scientific research focus is being paid to fossil fuel alternatives, such as solar cells. Solar cells directly converting sunlight into electric energy have various merits such as avoidance of contamination, infinite resource and semi-permanent lifespan, and are thus anticipated as an energy source capable of solving the problem of energy depletion. Solar cells are semiconductor devices for solar energy generation. Performance indicators determine the value of a solar cell, for example; spectral responsibility, open circuit voltage, short circuit voltage, short circuit current, conversion efficiency and maximum output. These performance indicators are determined by measuring photoelectric characteristics using a test called Standard Test Condition (STC). For common crystalline silicon solar cells, which have relatively good thermal conductivity, and thin film solar cell, the indirect method of controlling sample temperature is fully efficient to due effective heat exchange between a sample stage and a sample. However, in the case of a thin film solar cell using a thick glass substrate or a solar cell that has an additional jig for measurement, the heat exchange between a sample stage and a sample is not effective. The inefficiencies experienced when measuring solar cell properties, of some solar cells, arise due to the difficulty encountered when attempting to maintain the temperature of the measurement target solar cell at values similar to those prescribed by STC conditions. Also, in the case of a dye-sensitized solar cell, which requires a relatively long time for measurement, the cell must be exposed to light for a prolonged period, making temperature measurements difficult to attain as well as suffering issues because of prolonged photo-irradiation. The technology, developed and presented by the KIER, has been conceived to solve the problems related to controlling sample temperatures during photoelectric and solar cell measurements. This advanced technology offers a refined, indirect, method for controlling sample temperatures, and may be used for measuring various photoelectric and solar cell characteristics.

Researchers at the Korea Institute of Energy Research have developed a new method of managing the inherent limitations of heat pumps, in terms of their application for unpredictable heat energy sources. Heat pumps are devices that can produce hot water with a high temperature using a heat source with a low temperature. In general, heat pumps produce hot water with a set temperature and a set flow rate using a heat source that is introduced with both predetermined temperature and flow rate. However, with the increased use of new renewable heat sources, such as geothermal heat, sewage heat and solar heat; there is a need for heat pumps with the capacity to manage heat sources with characteristically unpredictable temperatures and flow rates that are prone to sudden change. What’s more, there is an increasing requirement for heat pumps capable of supplying hot water at varying temperatures, as opposed to one set temperature – to accommodate demand requirements. Conventional heat pumps are limited in their capability to sufficiently align the characteristics of heat sources and the characteristics of the demand source. Generally, demand sources for heat pump energy require both consistent temperatures and flow rates. Meaning that heat sources, such as renewables, which suffer unreliable temperatures and flow rates are generally unsuitable for heat pump use. The innovative broadband heat pump technology presented offers a unique system which can overcome the inherent limitations of heat pump technology. This technology enables the control of heat source temperatures in order that heat supplied is at a uniform temperature and can be tailored to meet the requirements of the demand source. This broadband heat pump technology has several beneficial implications. Notably the pump is capable of being supplied with hot water with various levels of temperature, which can then be supplied to any desired demand source. Additionally, since heat sources with varying levels of temperature, notably including renewable energy sources, can be used, energy availability increases, and the pump offers a gateway for renewable energy use.

The present technology relates to a process and apparatus for recovering high-purity olefin from mixed gasses containing light olefins (ethylene, propylene, etc.). Olefin is a long chain polymer synthetic-fibre created when ethylene and/or propylene gases are polymerized under specific conditions. The resultant material, olefin, has a myriad of applications in manufacturing, household products, clothing and petrochemical products including plastics and packaging. Due to the non-toxicity of olefin in water, as well as the structural stability of materials manufactured using olefin fibre, the material, in its purest form, offers numerous advantages to different sectors and in several industrial processes. Generally, distillation techniques have been used to separate olefin/paraffin mixtures. However, significant challenges arise during these conventional distillation processes due to the small difference in boiling point between olefin and paraffin, and the subsequent requirement that distillation columns must have several distillation trays. This requirement later incurs high energy and equipment costs. In recent years, technology advancements have enabled the reduction in olefin separation costs by using a process of separating olefin by absorption as opposed to the traditional method of separation through distillation. This advanced olefin separation technology builds on the capabilities of recently developed absorption methods, through the addition of a sophisticated displacement desorption process of desorbing absorbed ethylene using a desorbent. Light olefins production is a multi-billion-dollar commodity industry, and the olefin separation process is the most energy-intensive operation in the production of ethylene, propylene and other high-volume olefin petrochemicals. Using this patented displacement-desorption process the high energy requirement of olefin separation can be reduced, thus saving resources and improving economic efficiency.

Researchers at the Korea Institute of Energy Research have developed a new apparatus for producing silicon nanocrystals based on inductively coupled plasma. Silicon nanocrystals have been widely investigated for several years because of their many interesting properties and potential use in several applications. Recently, silicon nanocrystals have been used in solar cells and light emitting device (LEDs). Silicon is an environmentally friendly material and is utilised for various applications in the field of electronic materials. The field of silicon nanocrystal production has grown enormously of late, in response to the observation of quantum confinement in porous silicon. Silicon is already widely used in the semiconductor industry, in large part because of its nontoxic properties and abundance, being the second most abundant element in the earth’s crust. Due to the high capacity of silicon paired with its relatively environmentally friendly properties it is an ideal material for use as a replacement to more commonly used environmentally costly materials. The common process of producing silicon nanocrystals can be classified into three distinct areas: solid-state reaction, liquid state reaction, and vapour state reaction. The solid-state reaction is the process whereby a thin film of SiO2, Si3N4 or the like containing excess Silicon (Si) is formed and subjected to heat treatment to enable the condensation of silicon and subsequent formation of silicon nanocrystals in a SiO2, Si3N4 or SiC matrix. In the liquid state reaction, silicon nanocrystals are prepared via a chemical reaction of silicon compounds, this is done through the application of variant methods, for example the high-temperature supercritical method. In the vapour state reaction, silicon nanocrystals are prepared by passing a silane compound gas through a high energy region such as laser or plasma. In the case of all three traditional silicon nanocrystals reaction methods (solid, liquid and gas) the process incurs significant cost due to the substantial need for heat energy and expensive deposition equipment. What’s more, in the liquid State reaction issues arise due to the severe difficulty in controlling particle size, which in turn leads to poor crystallinity quality. The vapour state reaction incurs further issues due to the extreme use of energy resulting in aggregated nanocrystals and the formation of secondary particles. To overcome the inherent issues of solid, liquid and vapour silicon nanocrystal reactions non-thermal plasma, such as inductively coupled plasma (IPC) has begun to be used. However, the conventional ICP-based apparatus has limitations and can result in issues pertaining to the management of the particle size of silicon nanocrystals, as well as extending reaction time and deteriorating silicon nanocrystal quality. To combat the aforementioned limitations in silicon nanocrystal production a new apparatus method has been designed, which can minimise plasma diffusion inside the reactor during production using ICP to improve the particle size characteristics and quality of the silicon nanocrystals.
