Electron diffusion at Sn perovskite/fullerene derivative interfaces and its influence on open-circuit voltage

Abstract Tin-based perovskite solar cells (PSCs) are the most promising alternatives to toxic lead-based ones. However, the loss in open-circuit voltage (V OC) remains an important issue. Improvement of V OC has been achieved by using a fullerene derivative, indene-C60 bisadduct (ICBA), as the elect...
