Abstract
The present status of (CdZn)S/Cu2S thin film solar cells is reviewed. A new source design has been used to improve the (CdZn)S films. Light reflection loss has been reduced to ∼ 5% by texturing the (CdZn)S surface prior to Cu2S formation. Using 90% transparent grids, current densities over 16 ma/cm2 and open circuit voltages over 0.7 volts have been obtained, with a best power conversion efficiency of 6.29%.
