Discontinuous SnO2 derived blended-interfacial-layer in mesoscopic perovskite solar cells: Minimizing electron transfer resistance and improving stability

We put forward a new and rational ETL architecture for M-PSCs by creating a blended interface involving four components of FTO, SnO2, TiO2 and perovskite, which were strongly coupled and more advantageous for transfer of photoinduced electrons.276
