Summary / Abstract: The organic−inorganic perovskite solar cells (PSCs) have gained the certified power conversion efficiency (PCE) of 25.2%, making it a competitive candidate for the next generation solar cell of industrialization. However, the stability, especially to the long-term thermal stability, stills far more lagging behind of the improvement of PCE. The all−inorganic PSCs is regarded to offer a feasible solution to tackle the thermal instability issue of organic−inorganic PSCs. In this work, we designed a ZnO@C60 bilayer that was utilized as the electron transporting layers (ETLs) in the inverted all-inorganic PSCs. Further tailoring C60 via a co-doping strategy was carried out to enhance the electron extraction, leading to high efficiency inorganic CsPbI2Br perovskite solar cells and modules.
