CZTS-BASED COMPOUND SEMICONDUCTOR AND PHOTOELECTRIC TRANSDUCER

摘要

PROBLEM TO BE SOLVED: To provide a CZTS-based compound semiconductor which has a band gap different from that of a conventional CZTS-based compound semiconductor and a photoelectric transducer using the same.SOLUTION: In the CZTS-based compound semiconductor, the ratio of the number of moles of Cu is set to be larger than the ratio of the number of moles of Cu to the total number of moles of Cu, Zn and Sn constituting CuZnSnS; and the photoelectric transducer uses the CZTS-based compound semiconductor.
