CdS thin films have been prepared by using chemical bath deposition. T
he effects of bath temperature and concentration of NH4OH were studied
. Optimum deposition conditions were established. The resulted CdS thi
n films exhibit optical transmissions in excess of 90% over the majori
ty of the solar spectrum. ZnO/CdS/CuInSe2 solar cells were fabricated
on elcctrodeposited CuInSe2 thin films. A conversion efficiency of 6.3
% was obtained with an active area of 7.8 mm(2) (no AR coating).
