Paper Abstract

Polycrystalline thin films of CuInSe2 were electrodeposited on to titanium substrates from acidic baths. For polysulphide electrolyte containing NaOH, Na2S and S (each 1 m) these films show best photoresponse, when electrodeposited with 60 m mole sodium citrate concentration. Due to surface treatment these films show good photoelectrochemical behavior with high conversion efficiencies and stability. Chemical etching is found to improve short circuit current and fill factor, whereas photoelectrochemical etching technique improves the stability of photo-anode in polysulphide solution. The efficiency is 4.04% and 3.5 and fill factor is 0.57 and 0.49 for chemically etched and unetched CuInSe2 thin films, respectively.
