Cadmium telluride (CdTe) solar cells are a leading thin film technology with relatively high efficiencies. However, even the highest published efficiency CdTe cell is well below the theoretical achievable efficiency. Atomic scale characterization wou

Cadmium telluride (CdTe) is a leading absorber for thin-film solar cells. However, state-of-the art open circuit voltages (V oc ) of CdTe thin film solar cells fall ∼350 mV below the value expected based on the band gap of CdTe. One of the reasons
