A high-performance hole-transporting layer (HTL)-free conventional perovskite/fullerene heterojunction thin-film PVSC was demonstrated. Here, we revealed that perovskite can modify the work function of ITO, leading to sufficient charge extraction efficiency at the ITO/perovskite interface. Combined with the high conductivity of ITO, a PCE of >11% with a high open-circuit voltage (Voc) of 1.01 V was achieved.
