Targeting the imperfections at the ZnO/CsPbI2Br interface for low-temperature carbon-based perovskite solar cells

In this work, cesium salts with functional anions of acetate (Ac − ), fluoride (F − ) and trifluoroacetate (TFA − ) are explored to modulate the deposition of ZnO films in low-temperature carbon-based CsPbI 2 Br perovskite solar cells.
