【 摘 要 】

In the paper a generalized equivalent circuit based on the SPICE model of a multijunction solar cell allowing forming and studying current-voltage characteristics is presented. The negative effect of the low shunting resistance on determining true values of a subcell current at different mismatches of p-n junction photocurrents in measuring a spectral dependence of photosensitivity was investigated.
