Molecular materials with high structure-design freedom are used as new interface passivators to reduce nonradiative recombination in inverted perovskite solar cells (PSCs). However, most molecular modifiers unable achieve a long-term passivation effect due self-aggregation. Here, the modifier 1-methyl-2-thiomethyl-1H-imidazole-5-carboxylate (SMC) ester and thiol groups is carefully developed. The weaken self-aggregation triggered by intermolecular hydrogen bonds, making such aggregations easier disassemble during heating form net-like insulating layer random openings, which dramatically increase charge transport. More importantly, electron transfer between disulfide can accelerate elimination of Pb0 I2 redox reactions prevent phase separation. Ultimately, optimized PSCs bandgaps 1.68 1.55 eV showed surprising fill factors 84.83% 86.18%, resulting champion efficiencies 23.45% (certified 22.98%, highest date for wide-bandgap) 25.71% 25.28%), respectively. Remarkably, both unencapsulated devices maintained over 94% their initial efficiency under maximum power point tracking 600 h (50 °C) 1000 (65 °C), respectively, confirming impressive operational stability.

Abstract Tandem solar cells (TSCs) based on wide bandgap (WBG) perovskites have gained significant attention for their higher power conversion efficiency (PCE) compared to single‐junction cells. The role of WBG perovskite (PSCs) as the sub‐cell in tandem consists absorbing high‐energy photons and producing open‐circuit voltages ( V OC ). However, PSCs face serious phase separation issues, resulting poor long‐term stability substantial loss TSCs. In response, researchers developed a range strategies mitigate these challenges, showing promising progress, comprehensive review is expected. this review, we discuss mechanism organic–inorganic hybrids all‐inorganic perovskites.

Abstract Cesium lead triiodide (CsPbI 3 ) perovskite receives tremendous attention for photovoltaic applications, owing to its remarkable thermal stability and optoelectronic properties. However, realizing the CsPbI with high black‐phase properties remains a significant challenge, which largely affects performance of solar cells (PSCs). Herein, aromatic ammonium agents are used modulate crystallization improve efficient PSCs. Systemically experimental studies comprehensively theoretical calculations performed, reveal that histammonium dihydrochloride (HACl 2 could strongly couple during crystallization, leading faster nucleation slower growth, thus modulating dynamics perovskites. Moreover, residual diammonium cations (HA 2+ distributed at grain boundaries on surface perovskites can effectively passivate defects through electrostatic interactions, substantially suppressing trap‐assisted nonradiative recombination, prompting more matched energetics. Consequently, PSCs is improved because combination enhanced crystallinity This work offers new avenue prepare inorganic photovoltaics.
