Abstract
CuInSe2 thin films were prepared on SnO2-coated glass by electrodeposition from aqueous solution containing CuCl2, InCl3 and SeO2. The deposition was carried out by varying cathode potential. It was found that the Cu/In ratio which influences CuInSe2 characteristics greatly can be controlled by the cathode potential. Annealing of as-deposited films in N2 atmosphere at 350°C was found to result in the formation of CuInSe2 films having a chalcopyrite structure. With the use of these annealed CuInSe2 thin films, CdS/CuInSe2 thin-film solar cells were formed as a preliminary step and the conversion efficiency of 1.49% was obtained.Keywords
