[Abstract]:Quaternary sulfide-copper-zinc-tin sulfur (CZTS) is a new thin film solar cell material with a zinc-yellow tin structure, a p-type conductivity, a band gap of about 1.5 EV and an optical absorption coefficient of more than 104 cm ~ (-1). These characteristics are consistent with the solar spectrum. For these reasons, CZTS thin film is a new kind of thin film solar cell material which is expected to be low cost and can be developed on a large scale. The properties of CZTS and the device structure of thin film solar cells are briefly described. The research progress in the preparation of CZTS thin films by sol-gel method and their corresponding device efficiency are introduced in detail. Finally, the key technical problems of preparing CZTS thin film and its related battery performance are summarized, and the effective improvement measures are put forward, and the future research of CZTS thin film solar cell is prospected.
