The primary goal of this program, increasing the conversion efficiency of a thin-film cell based on CdS/Cu/sub 2/S, has been achieved. A number of (CdZn)S/Cu/sub 2/S cells have been made with conversion efficiencies in excess of 10% when tested in collimated sunlight. The highest efficiency achieved was 10.2% for a cell with 16% Zinc which had the following parameters; V/sub oc/ = 0.60V, J/sub sc/ = 22.8 mA/cm/sup 2/ (pro-rated to 100 mW/cm/sup 2/) FF = 74.9%. Further improvement in the performance of CdS/Cu/sub 2/S cells beyond the previously reported 9.2%, was found to be limited by deficiencies in the fundamental knowledge and control of the Cu/sub 2/S layer. A number of process changes in the production of CdS/Cu/sub 2/S cells have been explored and are reported on. Transient capacitance measurements on CdS/Cu/sub 2/S cells and further development of an integral encapsulation are also reported.
