The enhancement of greenhouse gases due to the increased usage of fossil fuels leads to global warming followed by climate change. To overcome these researchers have been concentrating on renewable energy. Solar energy is an inexhaustible source of energy. It could supply all the present and future energy needs of the world. The amount of solar radiation reaching the earth differs from the radiation reaching the top of the earth’s atmosphere. Flat-plate collectors are used to collecting solar energy and the collected energy is stored in different types of energy storage systems and used for different applications like water heating systems, thermoelectric systems. Solar cells are used for the direct conversion of solar energy into electrical energy. In this study, the importance of more economic hybrid thin films for application in the field of solar cells and photodetectors were highlighted. The optical absorption and photoconductivity for the hybrid thin films were found to increase with increasing concentration of zinc telluride.
