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 Despite significant progress in improving the photovoltaic efficiency of perovskite solar cells (PSCs), achieving long‐term operational stability remains challenging for their commercialization. Light‐induced halide ion migration causes instability, oxidizing iodide into iodine. Elevated temperatures exacerbate this issue, resulting irreversible device degradation. Here, ammonium oxalate (AO) is introduced as an additive to precursor prevent both degradation and photo‐induced pathway formamidinium PbI 2 films. AO stabilizes by inhibiting oxidation ions (I − ) passivates charged traps through coordination hydrogen bonding interactions, thereby enhancing crystallinity reducing defects within resultant This leads achievement a higher‐quality film with low trap density extended carrier lifetime. In addition, I inhibited, corrosion on silver electrode operating device. Consequently, champion power conversion (PCE) PSCs increased from 22.19% 24.82%. Meanwhile, air, thermal, light are also enhanced.

Abstract Compared to conventional structure inorganic perovskite solar cells (PSC), the power conversion efficiency (PCE) of inverted devices still falls behind. In structures, commonly used hole transport layer (HTL), nickel oxide (NiO x ), is hindered by low carrier efficiency. To address this issue, nanoparticles with potassium hexafluorosilicate (KSiF 6 ) in CsPbI 3 are modified. The high electronegativity KSiF leads an increased content Ni ⁺ NiO , greatly enhancing electrical conductivity. Meanwhile, (K) from modified HTL diffuses into after annealing, which further passivates defects at grain boundaries. As a result, PCE 19.8% achieved under ambient air conditions, open–circuit voltage ( V OC significantly increasing 1.14 1.21 V.

Abstract Amid the rapid advancement of formamidine (FA)‐based perovskite solar cells (PSCs), methylammonium chloride (MACl) has emerged as a pivotal molecule, widely recognized in achieving high‐efficiency PSCs. However, precursor solution (PPS), particularly after prolonged storage, deprotonated MA⁺ (MA 0 ) undergoes cationic addition with FA⁺, leading to relative depletion FA⁺ and reduction crystalline phase purity. Herein, using Piperazine‐2‐carboxylic acid dihydrochloride (PCADCl) inhibit deprotonation by forming strong two‐point hydrogen bonds between piperazine's amine groups proton (H⁺) MA⁺is proposed, thereby extending shelf life PPS. Furthermore, COOH PCADCl furtherly suppress while promoting coordination unbound Pb 2+ , reducing film defects improving purity phase. Additionally, energy level arrangement PSCs is improved. Benefiting from this strategy, PSC fabricated modified PPS achieves an impressive efficiency 25.56% retains 96% its initial performance aging for 20 days. Moreover, unencapsulated device 97% over 1300 h. This work significantly advances process development scientific research, representing crucial step toward large‐scale production commercialization
