Wide-bandgap (WBG) perovskites with high Br content suffer from halide segregation owing to defect-promoting ion migration. The resultant phase causes energy and charge transfer Br-rich I-rich areas, resulting in a large voltage loss WBG perovskite solar cells (PSCs). Herein, we report the multifunctional effects of trivalent metal chloride doping on efficiency, stability, PSCs, which were monitored by using situ photoabsorption photoluminescence (PL) spectroscopy. Among examined dopants (BiCl3, SbCl3, InCl3), InCl3 effectively passivated surface grains prevented addition small amount (1 mol %) precursor solutions. Consequently, In-doped FA0.8MA0.15Cs0.05PbI2Br PSC (FA: formamidinium; MA: methylammonium; band gap: 1.73 eV) improved its power conversion efficiency 16.06 17.54% passivation enhanced electron at bottom interface. Furthermore, exhibited dramatically stability during storage scanning. Our work highlights critical role formation films their electronic properties, offering way improve stabilize PSCs.

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.
