Abstract Although perovskite solar cells (PVSCs) have achieved rapid progress in the past few years, most of high‐performance device results are based on doped small molecule hole‐transporting material (HTM), spiro‐OMeTAD, which affects their long‐term stability. In addition, some defects from under‐coordinated Pb atoms surface films can also result nonradiative recombination to affect performance. To alleviate these problems, a dopant‐free HTM donor‐acceptor polymer, PBT1‐C, synthesized...

Abstract Wide‐bandgap perovskites have attracted substantial attention due to their important role in serving as a top absorber tandem solar cells (TSCs). However, wide‐bandgap perovskite (PVSCs) typically suffer from severe non‐radiative recombination loss and therefore exhibit high open‐circuit voltage ( V OC ) deficits. To address these issues, 2D octyl‐diammonium lead iodide interlayer is adopted onto the hole‐transporting layer induce formation of an ultrathin quasi‐2D that close...
