Abstract

The first step to understand the origin of losses in any photovoltaic solar cell is to determine the fundamental thermodynamic efficiency and voltage limits of such a device. In this contribution, we detail techniques to calculate the voltage limit in the case of cadmium selenium telluride (CdSeTe) solar cells, and how approaches based on bandgap alone - i.e., the Shockley-Queisser approach with step-function absorptance - can overestimate the thermodynamic open-circuit voltage limit V_{oc,ideal}. This is particularly true for arsenic-doped samples, which tend to exhibit below-bandgap absorptance.
