The organic–inorganic halide perovskite solar cell (PerSC) is the state‐of‐the‐art emerging photovoltaic technology. However, the environmental water/moisture and temperature‐induced intrinsic degradation and phase transition of perovskite greatly retard the commercialization process. Herein, a dual‐functional organic ligand, 4,7‐bis((4‐vinylbenzyl)oxy)‐1,10‐phenanthroline (namely, C1), with crosslinkable...
Lead‐free perovskite emitters, particularly 2D tin (Sn) halide perovskites, have attracted considerable academic attention in recent years. However, the problems of Sn oxidation and rapid crystallization lead to an inferior perovskite morphology with high trap states, thus limiting the luminous efficiency of Sn halide perovskite light‐emitting diodes (PeLEDs). In this study, the authors establish...
Layer‐by‐layer (LBL) deposition strategy enabling favorable vertical phase distributions has been regarded as promising candidates for constructing high‐efficient organic photovoltaic (OPV) cells. However, solid additives with the merits of good stability and reproducibility have been rarely used to fine‐tune the morphology of the LBL films for improved efficiency and stability. Herein, hierarchical...
Improving power conversion efficiencies (PCEs) and stability are two main tasks for organic photovoltaic (OPV) cells. In the past few years, although the PCE of the OPV cells has been considerably improved, the research on device stability is limited. Herein, a cross‐linkable material, cross‐linked [6,6]‐phenyl‐C61‐butyric styryl dendron ester (c‐PCBSD), is applied as an interfacial modification layer...
