Abstract :
Solar cells were fabricated on evaporated CuInGaSe2 thin films by depositing thin CdS layers from aqueous solutions and subsequently depositing indium tin oxide (ITO) by DC sputtering. The CdS thickness was varied, and its effect on device quality was studied. The blue response of the cells showed improvement when a thin CdS layer was used, but the cell performance was affected by shunt leakage. Using a thick, solution-grown CdS layer, devices with 8.3% efficiency were fabricated
