Abstract : The objectives of this phase were (1) to improve the characteristics of chemically sprayed, large area, thin film solar cells from the standpoint of efficiency, weight and lifetime, and (2) to fabricate for delivery a one-foot square photovoltaic array. Research during the second phase was primarily directed to extending this feasibility of material and process to the fabrication of a solar cell using metal foil as a substrate. This research also covered the demonstration of heterogeneous junction photovoltaic effect using chemically sprayed films with Si, CdTe, and GaP. One photovoltaic thin film CdS array one-foot square was fabricated for delivery. The array which was composed of nine cells, each approximately four inches square, had an efficiency of .03%. This efficiency does not indicate the potential of the process since single four inch square cells were made with .3% efficiency and one inch square cells with an efficiency of 1.2%. (Author)
