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 Recently, the inverted CsPbI 3 perovskite solar cells (PSCs) have attracted extensive attentions due to their potential combine with silicon for tandem devices theoretical power conversion efficiency (PCE) of 44%. However, reported self‐assembled molecules (SAMs) as hole selected layer PSCs poor wettability and serious agglomeration, which greatly limits stability PSCs. To address above problem, niobium pentachloride (NCL) is applied prevent SAMs agglomeration a homogenous film hydrophilic surface. The optimized surface facilitates deposition cesium lead triiodide (CsPbI )film an enhanced referred orientation, suppressed defects, released stress. Consequently, NCL‐treated achieved champion PCE 21.24%, highest value all‐inorganic device maintained 97.61% initial after 1000 h storage in air, 92.27% tracking at maximum point (MPP).

Abstract The regulation of interfaces remains a critical and challenging aspect in the pursuit highly efficient stable perovskite solar cells (PSCs). Here, 2,2′‐bipyridyl‐4,4′‐dicarboxylic acid ( HBPDC ) is incorporated as an interfacial layer between SnO 2 layers PSCs. two carboxylic moieties on bind to through esterification, while its nitrogen atoms, possessing lone electron pairs, interact with uncoordinated lead (Pb 2+ atoms Lewis acid‐base interactions. This dual functionality enables simultaneous passivation surface defects both buried layers. In addition, electron‐deficient nature enhances energy band alignment facilitates transfer from . Furthermore, incorporation strengthens adhesion, improving mechanical reliability. As result, PSCs exhibited impressive power conversion efficiency (PCE) 25.41 % under standard AM 1.5G conditions, along remarkable environmental stability.

Abstract Tin perovskite solar cells (PSCs) have garnered considerable attention as promising alternatives to lead PSCs due their lower toxicity and outstanding optoelectronic properties. However, efficiency stability, particularly in 2D/3D tin PSCs, are usually hindered by high defect densities inefficient carrier transport. In this study, a small‐molecule Lewis base with multiple functional groups‐cyanoacetohydrazide (CAH) is employed mitigate defects enhance charge transport PSCs. It revealed that the carbonyl, amine, cyano groups CAH form strong chemical bonds Sn 2+ ions, resulting synergetic coordination effects. Moreover, interaction between effectively regulates crystallization process of film, high‐quality film enhanced crystallinity, reduced density, modulated phase distribution. As result, optimized achieve remarkable power conversion 15.06%, marking one highest values for Furthermore, devices exhibit retaining 95% initial performance after 2000 h storage nitrogen atmosphere.

Despite the outstanding power conversion efficiency of perovskite solar cells (PSCs) realized over years, entire lifecycle from preparation and operation to discarding PSCs still needs be carefully considered when it faces upcoming large-scale production deployment. In this study, bio-derived chitin-based polymers are employed realize full regulation air-processed by forming multiple coordinated hydrogen bonds stabilize lead iodide organic salt precursor inks, accelerating solid-liquid reaction crystallization two-step deposition process, then achieving high crystalline oriented perovskites with less notorious charge defects in open air. The air-prepared exhibit a decent 25.18% reproducibility improved operational stability toward harsh environment mechanical stress stimuli. modified display negligible fatigue behavior keeping 92% its initial after operating for 32 diurnal cycles (ISOS-LC-1 protocol). Meanwhile, closed-loop management end-of-life including suppression leakage, toxicity evaluation broken devices, recycling components comprehensively investigated. This work sheds light on promising avenue efficient stable PSCs.
