Abstract Efficiency, stability, and cost are crucial considerations in the development of photovoltaic technology for commercialization. Perovskite solar cells (PSCs) a promising third‐generation due to their high efficiency low‐cost potential. However, stability organohalide perovskites remains significant challenge. Inorganic perovskites, based on CsPbX ₃ (X = Br − /I ), have garnered attention excellent thermal optoelectronic properties comparable those perovskites. Nevertheless, inorganic faces several hurdles, including need high‐temperature annealing achieve photoactive α‐phase susceptibility transitioning into nonphotoactive δ‐phase under environmental stressors, particularly moisture. These challenges impede creation high‐efficiency, high‐stability devices using low‐cost, scalable manufacturing processes. This review provides comprehensive background fundamental structural, physical, lead‐halide It discusses latest advancements fabricating PSCs at lower temperatures ambient conditions. Furthermore, it highlights progress state‐of‐the‐art devices, manufactured environments reduced temperatures, alongside simultaneous upscaling PSCs.

Abstract Perovskite quantum dots (PQDs) become a kind of competitive material for fabricating high‐performance solar cells due to their solution processability and outstanding optoelectronic properties. However, the current synthesis method PQDs is mostly based on binary‐precursor method, which results in large deviation I/Pb input ratio reaction system from stoichiometric PQDs.

Recent developments in perovskite-silicon tandem solar cells (TSCs) have been quite remarkable. Inorganic perovskite (IPSCs) are gradually emerging as the top device. However, IPSCs generally suffer from a severe open-circuit voltage (VOC) deficit, limiting their efficiency gains and application TSCs. Here, we developed surface defect clipping strategy using pyridyl-2,6-dicarboxamide (PD) methanol solution. The proper polarity of solution will clip upper inorganic film provide corresponding path for penetration PD In addition, efficiently situ passivate uncoordinated Pb2+. After annealing, dense films were formed on perovskite. crystallization dynamics perovskites near is regulated, nonradiative recombination effectively suppressed. Eventually, record VOC 1.259 V (1.71 eV) achieved based inverted IPSCs, deficit only 450 mV. More importantly, unencapsulated IPSC devices show significantly enhanced thermal humidity stability.

Metal-halide inorganic perovskites have gained great interest due to their excellent thermal stability and adjustable bandgaps for fabricating tandem solar cells. However, challenges such as significant nonradiative recombination by perovskite interfacial defects unpleasant moisture forced further improvements in the power conversion efficiency (PCE) of inverted cells (PSCs). Herein, 3,5-bis(trifluoromethyl)benzylamine (TFBA) a surface modifier was used achieve these goals. It found that amino group TFBA can provide electrons coordinate with undercoordinated Pb2+ on perovskite, thus mitigating defects. Moreover, contains two trifluoromethyl groups hydrophobic properties, which effectively prevent from intrusion. Consequently, treatment resulted remarkable improvement device open-circuit voltage 110 mV, leading PCE 20.4% under 100 mW cm–2 illumination, superior control cell (17.8%).
