All-inorganic perovskite solar cells provide a promising solution to tackle the thermal instability problem of organic-inorganic (PSCs). Herein, we designed an all-inorganic cell with novel structure (FTO/NiO x/CsPbI2Br/ZnO@C60/Ag), in which ZnO@C60 bilayer was utilized as electron-transporting layers that demonstrated high carrier extraction efficiency and low leakage loss. Consequently, as-fabricated CsPbI2Br yielded power conversion (PCE) 13.3% Voc 1.14 V, Jsc 15.2 mA·cm-2, FF 0.77. The...
