Technology engineering company posted this:Solar energy harvester based on optical rectenna, efficiency factor better that 50%The world problem that energy sources like coal, oil and gas are finite and spoiling ecology. Solar is a tremendous source of renewable and clean energy. Silicon monocrystal solar cell efficiency factor is 20%.47% of energy goes for heating solar cell, this effects to reduce efficiency factor. So we collect only small part of solar energy, that is 23 000 TWy. Especially in deserts.
Universitat Politècnica de Catalunya - UPC posted this:New strategy for local diffusion of dopants in crystalline siliconA new methodology to replace conventional diffusion processes has been developed and patented. This simple procedure offers a wide versatility, since it allows the creation of locally doped regions without photolithography steps while simultaneously reducing the global thermal budget of the emitter creation process. The potential of the method has been already confirmed for silicon solar cell applications. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.
Universitat Politècnica de Catalunya - UPC posted this:Multilevel Active-Clamped Electrical Energy ConverterA new multilevel conversion technique has been developed to produce efficient, compact, and easily scalable electrical energy converters to be employed in dc-dc, dc-ac, and ac-ac, single- or multiple-phase, conversion applications with unidirectional or bidirectional power flow. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.
Consejo Superior de Investigaciones Científicas posted this:Organic derivatives for the manufacture of electronic devicesCSIC have developed organic derivatives, low cost, with possibility of modifying its molecular structure, including different substitutions, improving the properties of electronic semiconductor. These molecules present not only interesting electronic properties which make them active for the manufacture of solar cells, specifically organic photovoltaic cells, but also an intense blue color which allows it so be used as a dye in the textile industry. Industrial partners from the energy, electronic and textile are being sought to collaborate through a patent licence agreement. An offer for Patent Licensing
Universidad de Alicante posted this:Stand-alone system for the purification of brackish water directly powered by photovoltaic solar energyThe Applied Electrochemistry and Electrocatalysis Research Group at the University of Alicante has developed an Stand-alone system for the desalination and disinfection of water by Electrodialysis (ED) and the necessary water pre- and post-conditioning steps. The developed system is sustainable and environmentally-friendly being directly powered by a photovoltaic solar plant without using battery racks. This new system substantially decreases both the investment and maintenance costs by eliminating the batteries. Also, it can be adjusted to be used in water from very different sources like seawater, brackish water wells, wastewater treatment plants, industrial processes water, etc. being of particular interest for remote areas isolated from the electric grid. The Research Group has a demonstration Pilot Plant with the capacity to produce up to 1m3 of drinking water per day. The Group is looking for companies interested in the commercial exploitation of this technology through licensing agreements and/or technical cooperation.

Advantage of cooling the Photovoltaic System generating more power under high Global radiationSchwimmfähige Photovoltaikanlage / Floatable Photovoltaic System to produce Electric Energy using floatable Aluminum- plates in thermal contact with Photovoltaic Elements. Weather dependend heating of the Photovoltaic Elements will reduce their efficiency in producing Electric Energy. Cooling the Photovoltaic System (PV) down to receive Electric Power more effiently when exposed under high Global radiation. High Global Radiation (W/m²) could heat up PV e.g. to 60° C and result in a so called "Voltage drop". The Photovoltaic System combined in thermal contact with cooling elements could be used on air. Further Research on this matter is planned.
BPE e.K. posted this:Process for cooling Photovoltaic ModulesPhotovoltaic modules generating electric energy from global radiation often heat up under high global radiation values and loos electric power under these conditions, offen called voltage drop, We have developed different cooling methods which reduce temperature of photovoltaic modules and at the same time generate additional electric energy during cooling. For this cooling process we use thermogenerators. Based on weather situation cooling of photovoltaic modules could result in higher electric energy.
Technology Transfer Office
CITCEA-UPC posted this:Technology transfer in renewable energies, power electronics, energy control, electrical vehicles...CITCEA-UPC is a technology transfer center which was created in 2001 within the UPC (Universitat PolitÃ¨cnica de Catalunya, BarcelonaTech), and it is specialized in responding to electrical and electronic technological challenges. The aim of the center is to receive these challenges and solve them by creating a functional prototype that will serve the companies to eventually develop a new commercial product or to solve a new technological problem created by the growth and evolution of the society.
Universidad de Alicante posted this:Black titanias for photocatalysis, solar cells and environmental applications• The titania is black, and then absorb in the whole visible range (band gap 2.74 eV) and maintains its photocatalytic activity at least after 5 cycles reaction with an efficiency of 95 %. • The synthesis process is simple, inexpensive and versatile (a wide variety of functional compounds can be incorporated in the structure of the titania lattice avoiding blocking the mesoporosity and maintaining the anatase structure). • Excellent thermal and hydrothermal stability. The functionality is incorporated into the structure of the titania being protected thereby.
Universidad de Alicante posted this:New family of dyesThe main innovative aspects of this technology regarding current methods of synthesis are: • The indolizine dyes are obtained in one step from commercially available materials, unlike current procedures, which involve multiple steps. This is an advantage in the production process, as it reduces costs, increases the final yield and less waste is generated. • The procedure is based on a very simple treatment which produces indolizine dyes in yields higher than 70%. • The present invention does not require the use of inert atmosphere, dry solvents or physical activation (heat or radiation) to obtain the final product. • Unlike other methodologies for preparing indolizine dyes (requiring temperatures around 100°C), this process is carried out at room temperature and atmospheric pressure, which simplifies the method and decreases production costs. • This is an environmentally friendly technology because it does not use solvents such as dioxane, pyridine, chloroform or benzene, which are used in other methods and are characterized by their high toxicity and demonstrated carcinogenicity. • The selectivity of the reaction is very high. The indolizine dye is obtained with absolute control, obtaining a single isomer of the ten possible.
