a Energy-level diagrams for different hole transport materials (HTMs) and perovskite. b Time-resolved photoluminescence results of FAPbI3 film with different treatment. c J–V curve of PSC based on FAPbI3 film using Poly(vinylcarbazole) as HTM. The inset shows the certified steady-state efficiency of the perovskite solar cell (PSC). d Power conversion efficiency distribution of PSCs based on different perovskite films (20 devices for each type). The box plot denotes minima (bottom line), maxima (top line), median (center line), and 75th (top edge of the box) and 25th (bottom edge of the box) percentiles.
