Cuprous oxide photovoltaic cells. Second quarterly technical progress report, July 9-October 8, 1979

Research on the fabrication and characteristics of solar cells based on heterojunctions of Cu/sub 2/O with SnO/sub 2/, In/sub 2/O/sub 3/, CdO, and mixtures of CdO and SnO/sub 2/ is described. The Cu/sub 2/O samples were prepared by thermal oxidation of copper sheet and the other semiconductors were applied by ion sputtering. Current-voltage characteristics of the heterojunctions, Auger spectra of the top surfaces, and Auger depth profiles are presented graphically. (WHK)
