The theory of polycrystalline solar cells reported last quarter has been extended by introducing effects due to the reduction of grain boundary states. The results show that a large improvement in efficiency can be attained either by increasing the grain size or by passivating the grain boundary states to reduce the number of recombination centers. Experimental results are presented to show grain size distribution in Wacker polycrystalline silicon. Preliminary Hall mobility measurements are presented as a function of temperature. Experimental results and analysis of diffused p on n cells are reported. Preliminary studies of grain boundary passivation and stability of SnO/sub 2//n-Si, solar cells are presented.
