Abstract
Precise values of the reverse saturation currents in silicon solar cells and magnitudes of the diffusion and recombination components have been obtained. The recombination current as well as leakage current due to shunting are shown to be nonuniform across the cell. The diffusion lengths calculated from the diffusion current components agree well with diffusion lengths measured independently in similar material. Models are given demonstrating the effect of recombination and shunting currents on the dark current-voltage characteristics of solar cells
