The maximum short circuit for CdS/Cu/sub 2/S cell has now been increased to 21.9 mA/cm/sup 2/. Application of the redesigned grid structure is expected to yield CdS/Cu/sub 2/S cells with over 8% conversion efficiency. The short circuit currents achieved with the (CdZn)S/Cu/sub 2/S cells are showing marked improvement. Currents in excess of 12 mA/cm/sup 2/ have been achieved at open circuit voltages of 0.67 V and over 10 mA/cm/sup 2/ at open circuit voltages of 0.60 V. Direct experimental observations coupled with theoretical analyses have been conducted on the influence of the Cu/sub 2/S sheet resistivity on cell performance. Further refinements have been made in the theoretical analysis of fill factor. Spectral response and photocapacitance measurements have been made on the mixed sulfide cells.
