The degradation of electroplated cells has been closely observed and it has been found that recovery can be accomplished under proper conditions. Chemical milling of the substrate is an excellent method for producing high power to weight ratio cells. Fabrication of the one-half and one square foot mechanical sample arrays indicate improved total area utilization factors. Photovoltaic cells and diodes have been prepared by first depositing a thin film of CuCl on CdS. The CuCl was subsequently converted to Cu9,5S5 by means of H2S. Optical studies on electroplated and chemiplated barriers have served to confirm the presence of Cu2S alone or mixed with CuS. Thin layers of SiO have been utilized as a water vapor barrier to significantly decrease degradation of cells. Additional theoretical work has been performed on a heterojunction model of the cell operation. Author
