Hole Transfer Dynamics in Thin Films of Mixed‐Dimensional Quasi‐2D Perovskites
Charge transfer dynamics in quasi‐2D perovskite (PEA2MAn−1PbnI3n+1), grown with a distinct dimensionality gradient are investigated. Selective excitation of the n = 4 phase reveals efficient hole transfer to n = 2 and n = 3 within tens of picoseconds, while n = 1 acts as a hole‐blocking layer. These findings highlight the importance of minimizing n = 1

Metal chalcogenide electron extraction layers for nip-type tin-based perovskite solar cells
Tin-based perovskite solar cells have garnered attention for their biocompatibility, narrow bandgap, and long thermal carrier lifetime. However, nip-type tin-based perovskite solar cells have underperformed largely due to the indiscriminate use of metal ...
