Satbayev University scientists are working to reduce expenses of clean energy
Satbayev University scientists are developing new methods for the synthesis of antimony selenide thin films, which will reduce expenses of photovoltaic absorbing materials. Antimony selenide is used as a light-active layer to convert solar energy into electricity. Owing to its excellent optoelectronic properties, antimony selenide is actively used for manufacturing the solar panels and batteries, LEDs, photodiodes and photodetectors, etc.
Despite the availability of various synthesis methods, including liquid phase deposition, most of them have disadvantages, manifested in the low quality of the initial films and the high cost of production.
"Our technology will allow us to obtain high-quality material with the desired semiconductor properties and lower cost compared to analogues," says PhD Aigul Shongalova, head of Photovoltaic Phenomena and Devices Laboratory at Satbayev University Physics and Technology Institute.
Creation of high-quality structures of antimony selenides will make it possible to establish industrial production of the material in demand all over the world, which can significantly affect the solar energy availability. In addition to the practical part, the project also includes a theoretical study of the lattice dynamics of these materials that makes it possible to comprehend their thermal and vibrational properties at the molecular level.
