摘要：

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 degrees 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 degrees C whereas the secondary phases vanishing significantly at 550 and 650 degrees C. The optical studies indicated high absorption coefficient for CZTS in the range of 10(4)-10(5) 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.
