University scientists are working on creating solar batteries of new generation

Scientists of the South Ural state University (SUSU) work sosteniendola batteries for the new generation. To this end, the University together with the Institute of organic chemistry (Moscow) synthesize new photosensitizers that have not previously been able to. The introduction of this type of energy will be inexpensive, and analogues of this technology does not exist yet.

Feature of new type solar cells is their plasticity. As planned by the scientists, they can be given any shape, and thus easy to mount to any object, given the characteristics of designs, sizes and design. "Wrapped" in the image form can be as a ballpoint pen, and the whole building. If from the sun will "eat" cars, the level of gas contamination of the atmosphere will be reduced significantly. One of the key points of this difficult work is to find the conditions of the reaction element substitution of sulfur for selenium in the molecule of the photosensitive substance.



"This reaction is allowed to increase the efficiency of the photosensitizer, an estimated 3 times. In fact, the figure may change, for example, 2.5 or even 4. However, even with the increase in the ratio of at least 2 times the improvement will be significant! Now the existing elements provide the building with electricity only in areas where much light is, for example, the southern regions. New photosensitizers can be used in our dimly lit region", — says doctor of chemical Sciences, Dean of chemical faculty of the University, Professor Vyacheslav Viktorovich. Photosensitizers themselves - the only basis for development. For the successful manufacturing scientist will work on a number of materials from which to manufacture an improved solar cell. According to Vyacheslav Avdin here particularly useful would be experience of our colleagues from Scotland and the UK who are already interested in this development. The second direction is connected with nanostructured catalysts based on metal oxide compounds: "Catalysts of this type has been developed by us several years and we have had some success. Recently, it was determined that this type of catalysts are used for hydrogen energy, that is in the process of electrolysis of water with formation of hydrogen," says Vyacheslav Avdin. The bottom line is that the development will save costs and the final cost of hydrogen produced compared to the traditional way, where the production of hydrogen came out so expensive that its use for energy was impractical. An existing prototype of these catalysts in America, according to preliminary estimates of scientists 10 times reduces the cost of electrolysis of water. According to Vyacheslav Viktorovicha, to synthesise catalysts was not too difficult for our scientists, but now you need to elektrokhimicheskoe cell and to evaluate the effectiveness of reducing power consumption for electrolysis. published
