Abstract The cracks in flexible triboelectric nanogenerators (TENG) cannot naturally repair themselves during low‐temperature operation, which significantly restricts their practical applications. Yet, the development of elastomers capable self‐repair at low temperatures has remained a formidable challenge.

Abstract Tandem solar cells combining perovskite and silicon have witnessed rapid development in recent years. However, the top cell, utilizing wide‐bandgap as absorbers generally suffer significant open‐circuit voltage ( V OC ) deficit, particularly for inorganic perovskite, which poses a considerable obstacle to enhancing power conversion efficiency (PCE). Here, modulation strategy by using 2,6‐pyridinedicarboxamide (PC), crystallization kinetics of film can be effectively regulated, specifically manifested relatively longer annealing time air, resulting sufficient growth grains. Additionally, PC situ passivate uncoordinated Pb 2+ , suppressing non‐radiative recombination charge carriers. Eventually, record PCE 22.07% is achieved based on n–i–p (IPSCs), also demonstrate highest above 1.34 (1.71 eV bandgap). More importantly, unencapsulated IPSCs show enhanced thermal stability photostability. Furthermore, are applied perovskite/silicon tandem (IPTSCs), 27.27% an impressive 2.024 obtained.

Many studies have shown that the severe photoluminescence quantum yield (PLQY) loss at interface between perovskite and electron transport layer (ETL) is main cause of voltage in inverted solar cells (p-i-n PSCs). However, currently there are no effective situ passivation techniques to minimize this nonradiative recombination. Here, fluorinated pseudohalide ionic liquid (FPH-IL) 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) introduced into precursor formulation. EMIMTFSI can change dielectric environment energy-level arrangement by accumulating on top surface spontaneously forming dipoles. As a result, excitonic binding energy (Eb) recombination significantly reduced. At same time, TFSI- reduces formation vacancy defects stabilizes phase N-H⋯F hydrogen bonds FA+ C-F bond EMIMTFSI. Finally, EMIMTFSI-modified p-i-n PSCs achieve an excellent efficiency 24.81% with impressive open-circuit 1.191 V for 1.57 eV low-bandgap perovskite. In addition, modified devices maintain more than 95% PCE after continuous thermal aging 85 °C 500 h or illumination maximum power point 800 h. This work provides new idea minimizing non-radiative losses PSCs.
