Although great efforts have been devoted to enhancing the efficiency and stability of perovskite solar cells (PSCs), performance PSCs has far lower than anticipated. Interface engineering is helpful for obtaining high through control interfacial charge transfer in PSCs. This paper demonstrates that can be enhanced by introducing stable α-CsPbI3 quantum dots (QDs) as an interface layer between film hole transport material (HTM) layer. By synergistically controlling valence band position (VBP)...
