Abstract
An apparatus for determining solar cell characteristics includes a quantum efficiency measurement tool configured to measure an external quantum efficiency of the solar cell and a reflectivity measurement tool configured to measure the reflectivity of the solar cell. The apparatus also includes a capacitance measurement tool configured to measure the capacitance of the solar cell and a processor configured to calculate a diffusion length of the solar cell based on the measured quantum efficiency, reflectivity and capacitance of the solar cell.
