Using a computer simulation, we have calculated the dependence of efficiency of both single junction and tandem amorphous solar cells on the band gap of the active layers. We have also developed a simple expression to relate the open-circuit voltage of an amorphous solar cell to the ratio of the photoconductivity to dark conductivity of the intrinsic layer. This provides a powerful diagnostic tool for the evaluation of low band-gap amorphous materials.
