Abstract : This research was directed toward investigating the feasibility of a unique method of film deposition of II-VI compounds in the development of photovoltaic devices. A major portion of effort during the first period was concerned with laboratory apparatus for the following purposes: measurement of film thickness, optical properties, photovoltage and current, and characterization of films of CdS and CdSe were deposited by the chemical spray technique in a range of thicknesses. Maximum film thicknesses of up to 15 to 20 microns were possible while retaining physical uniformity and reproducibility. Conducting Layer: Films of SnO sub x, In203, In203:Sn and CdO were successfully deposited. SnO sub x and In203 had the widest transmittance window. Barrier Layer: Cu, Al, and Au were vacuum deposited as electrode materials to evaluate and characterize the various films of CdS and CdSe deposited on SnO sub x coated glass. (Author)
