Abstract : Experiments leading to an optimized design for N+/P and P+/N solar cells which are to be utilized in a terrestrial environment at a solar intensity of about 350 mW/sq cm are described. The same cell design is shown to be optimized for 100 mW/sq cm earth's surface solar intensities as well. It is found that the results of the experiments can be predicted from theory to a good approximation. Pilot line production of cells utilizing the optimized design is described and yield distributions are presented. Good efficiency yields are found to occur for both polarities, however the yield distribution of the P+/N cells is superior to that of the N+/P cells. The P+/N distribution peaks in the 13.5-14.0% efficiency range with a yield of 70% of the cells having an efficiency of 12.9% or greater. The yield distributions are discussed in the light of further analysis of the electrical characteristics of the cells. (Author)
