Abstract
The radiative recombination limit of photovoltaic power conversion under one sun terrestrial illumination is calculated for solar cells with lateral fluctuations of the band-gap energy. A simple analytical model quantifies the fluctuations by the standard deviation from the mean band gap. The calculated maximum efficiency decreases by 1.7% (absolute) for and by 6.1% for with respect to a uniform band gap.
