Abstract
We report here all polycrystalline thin film solar cells of Cu2S–ZnxCd1-xS and Cu2S–CdS prepared by solid state reaction. The efficiencies in the range of 4 to 5% have been obtained without antireflection coating. The improvement in open circuit voltage is observed in Cu2S–ZnxCd1-xS cell with little sacrifice in short circuit current. A comparison is also made with the solar cell ZnxCd1-xS–Cu2S prepared by spray pyrolysis and the electrical conversion efficiency about 1.0% is obtained.
