Maximum power conversion efficiency in actual sunlight for the CdS/Cu/sub 2/S cell has reached 8.55% and short circuit currents of 25.0 mA/cm/sup 2/ have been measured. The (CdZn)S/Cu/sub 2/S cell conversion efficiency has increased substantially to a maximum value of 6.29% at an open circuit voltage of 0.64 V. The major improvement in cell performance is in short circuit current which now exceeds 14 mA/cm/sup 2/ for open circuit voltages between 0.60 and 0.68 V. Specific attention has been paid to parameters limiting fill factor in the CdS/Cu/sub 2/S cell. The analysis of the mixed sulfide cell is being progressively refined and measurements on open circuit voltage stability, capacitance and the influence of heat treatment are reported.
