Metal halide perovskite quantum dots (PQDs) not only share the common feature of confinement effect found in traditional but also exhibit favorable characteristics materials, including defect tolerance and long exciton lifetime. Thanks to these merits, within ten years research development, dot-based solar cells (PQDSCs) have attained a certified power conversion efficiency (PCE) 18.1%, which is, however, still far below those market-dominant silicon bulk thin-film counterparts. In this...

Abstract Perovskite solar cells (PSCs) have witnessed an unprecedentedly rapid development, especially in terms of power conversion efficiency (PCE). However, the solution‐processed perovskite films inevitably possess numerous crystallographic defects (e.g., halide vacancies), which has been shown to incur non‐radiative charge recombination and ion migration, thus limiting enhancement PCE stability PSCs. Here, a novel dual metal (i.e., divalent monovalent ions) modification strategy is...
