A Two-Step Top Surface Passivation Strategy for n-i-p Wide-Band Gap Perovskite Solar Cells
{{output}}
Large open-circuit voltage (Voc) deficit in wide-band gap perovskites has long been an issue that restricts the performance of perovskite-based tandem solar cells. Herein, we proposed a two-step surface passivation (TSP) strategy to enhance the Voc of the wide... ...
