Abstract The formamidinium lead iodide (FAPbI 3 ) perovskite has emerged as a promising material for high‐efficiency photovoltaic applications. Although power conversion efficiency of more than 26% been achieved, stability issues have hindered its commercial application. In this study, the FAPbI under adverse conditions such humidity, oxygen, ultraviolet light, and temperature fluctuations is systematically reviewed. known effective strategies improving are discussed. Current studies shown that technologies doping, halide alloying, additive manufacturing engineering, interface modification identified in mitigating phase transitions enhancing environmental durability. Encapsulation technology further improves moisture heat resistance. Compared with other stabilization strategies, doping alloying can address effects narrowing absorption edge. Interface engineering an essential understanding mechanism, which will greatly improve problem practical application . This paper also looks forward to future research directions development trends.

Methylammonium chloride (MACl) additive is almost irreplaceable in high-performance formamidinium (FA) perovskite photovoltaics. However, the byproduct of methyl (MFA+) from reaction MA0 and FA damages compositional purity phase stability α-FAPbI3. The addition iodine (I2) to FAPbI3 precursor has been reported inhibit formation MFA+. Here, we systematically investigate effect MAI on films devices by using replace MACl I2. results demonstrate that produces more I3- precursor, which inhibits between MA thus blocks Meanwhile, MFA+ reduced due delayed evaporation caused its strong interaction with I3-, facilitating growth α-FAPbI3 an improved bottom morphology. It eliminates unreacted PbI2, forming a homogenized phase, facilitates ordered along (111) facet, enhancing charge transport increasing open-circuit voltage (VOC). optimized device shows 2% improvement PCE, VOC 1.050 1.103 V. Additionally, target retains 97% initial performance after 5495 min operation under maximum power point tracking, compared 82.3% 2000 for control device. This work provides insights into inhibiting byproducts induced MA-FA side following introduction MACl.

Achieving efficient and stable perovskite solar cells (PSCs) is challenging due to nonradiative recombination, ion migration, film instability. This study designs low-dimensional (LD) ligands─benzimidazole (BIZ), 1H-benzimidazole, 6-methyl-, (6-MeBIm), 6-(trifluoromethyl)-, (6-TFBIm)─to construct LD/3D heterojunctions. Compared with BIZ 6-MeBIm (constructing 1D/3D heterojunction), the 2D/3D heterojunction constructed by 6-TFBIm successfully passivated different defects, resulting in a significant reduction recombination improved carrier transport, leading power conversion efficiency (PCE) of 25.25%, outperforming control devices (PCE: 22.97%). The PSCs exhibit superior humidity thermal stability, maintaining structural integrity under harsh conditions. These results underscore role tailored LD ligands optimizing quality, charge paving way for high-performance durable PSCs.
