Abstract : The report describes research and development on thin film photovoltaic cells. GaAs, ZnSe, and CdTe films were prepared by vacuum co-evaporation of the elemental constituents. Measurements of resistivity, absorption edge, x-ray diffraction pattern and Hall effect are described. Photovoltaic barriers were prepared on CdTe thin films and ZnSe single crystals by reaction with an aqueous solution containing copper ions. Measurements of I-V curve and spectral response are given. Preliminary measurements in CdS and ZnSe single crystals by x-ray diffraction topography are discussed. (Author)
