✦ Synopsis

A fully automated spectral response system for solar cells has been developed and utilized in the study of CdS/Cu2S and Zn3P2 solar cells. Four types of measurements were carried out: (1) spectral response under bias light conditions to study the effects of light intensity and spectral content on cell response; (2) spectral response on thick absorbing layers to determine their diffusion length and absorption coefficient; (3) spectral response beyond the intrinsic absorption region to determine the internal photoemission barrier height; (4) the response at a given wavelength as a function of the voltage bias and light bias on the cell to determine the voltage dependence of the light-generated current and its effect upon the fill factor of the cell.
