Abstract
Copper, Zinc and Tin sulfides were synthesized by solution method employing Na2S as sulfur source. Individual sulfides were sulfurized in non-vacuum condition at 350°, 450°, 550° and 650 °C to obtain CZTS. Structural, optical and morphological analysis indicated major portion of CZTS along with secondary phases such as SnS2, SnS and Cu3SnS4 at 350° and 450 °C whereas the secondary phases vanishing significantly at 550° and 650 °C. The optical studies indicated high absorption coefficient for CZTS in the range of 104–105 cm−1. Electrochemical analysis demonstrated that the CZTS samples prepared by the current methodology could be very well used as absorber material in thinfilm solar cells.
