INVESTIGATION OF THIN FILM CADMIUM SULFIDE SOLAR CELLS.
Abstract
Research and development of a large area CdS, vacuum evaporated, thin film, flexible, lightweight, front wall solar cell was continued in an effort to improve the performance characteristics. Efficiencies were increased to a maximum of 5.1%. Power to weight ratios of 15 watts per pound are normal with 30 as a maximum. An upgrading procedure for low efficiency cells was developed. Test panels were submitted for a 30 day orbital space flight evaluation. Electron damage experiments indicate little effect on the CdS solar cells. X-ray techniques have been used to photograph dislocations in single crystal CdS. Current-voltage curves and spectral response data analyses resulted in a one-trap model of the CdS photovoltaic cell.
