Progress has been made on improving the photon efficiency of the planar CdS/Cu/sub 2/S solar cell. Current in excess of 20 mA/cm/sup 2/ have been achieved. Mixed sulfide solar cells responsive to heat treatment are now being produced. The morphology of the Cu/sub 2/S/CdZnS junction has been examined and found to be significantly different than the morphology on CdS/Su/sub 2/S cells. Efficiencies measured under ELH simulation approaching 8% have been achieved. Work in the analytical task has focused on establishing the experimental techniques to study the trap levels in the CdS and to provide a working model for the voltage instabilities in some (CdZn)S/Cu/sub 2/S cells. Cells under roof top exposure continue to be monitored.
