Korea Institute of Energy Research posted this:Device for controlling sample temperature during photoelectric and solar cell measurementResearchers 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.

The combination of those data, makes it possible to easily locate vehicles in the car park regardless of their type or size and the environmental conditions / lighting (e.g. at night). The research group looks for town halls and companies in charge of the management/administration of car parks, to reach license agreements, collaboration agreements or commercial agreements with technical assistance. There is a great added value in an application that combines the knowledge of the free spaces and the vehicles in movement through the parking so it can provide the right indications to the user guiding him to a free space.

The invention comprises a block for discriminating and conditioning the signal detected by the photomultipliers, as well as a storing, coincidence, logic and trigger block, and a block for activating the output signals for generating the sounds and light flashes. The system includes different configurations for modifying the coincidence logic module so as to obtain different operation modes. The operation modes may condition the outlet of sound and light by means of logic operations. Said operation modes facilitate the implementation of different activities focused on the scientific disclosure such as exhibitions, museum display rooms or school laboratories.

It is conceived as a complement to the classic optical systems of license plate recognition for applications of traffic management, access control or detection of infractions, providing useful information relative to the brand of the vehicle whose license plate, previously or subsequently, has been detected. The research group looks for companies / institutions / administrations in charge of traffic control, access control to restricted areas, as well as those in charge of integrating vehicle violation detection systems, for the signing of collaboration agreements, license agreements or commercial agreements with technical assistance.
