Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

open access: yesAngewandte Chemie International Edition, EarlyView.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

1D/3D Heterojunction for High‐Efficiency Hole‐Transport Layer‐Free Carbon‐Based Wide‐Bandgap Perovskite Solar Cells

open access: yesCarbon Energy, EarlyView.
By modifying wide‐bandgap high‐Cs perovskite surfaces with quaternary ammonium salts of varying alkyl‐chain lengths, tetrapropylammonium bromide (TPABr) is shown to successfully construct a 1D/3D heterojunction. This structure effectively passivates interface defects and optimizes energy level alignment, achieving a champion efficiency of 20.14% with ...
