Abstract It is certain that perovskite materials must be a game‐changer in the solar industry as long their stability reaches level comparable with lifetime of commercialized Si photovoltaic. However, operational cells and modules still remains unresolved, especially when devices operate practical energy‐harvesting modes represented by maximum power point tracking under 1 sun illumination at ambient conditions. This review article covers from fundamental aspects instability including chemical decomposition pathways light soaking electrical bias, to recent advances techniques effectively prevent such degradation modules. In particular, causes for permanent due ion migration trapped charges are overviewed explain interplay between ions charges. Based on mechanism, strategies discussed slow down during operation use perovskite‐based devices.

All-perovskite tandem solar cells are attracting considerable interest in photovoltaics research, owing to their potential surpass the theoretical efficiency limit of single-junction cells, a cost-effective sustainable manner. Thanks bandgap-bowing effect, mixed tin-lead (Sn-Pb) perovskites possess close ideal narrow bandgap for constructing matched with wide-bandgap neat lead-based counterparts. The performance all-perovskite tandems, however, has yet reach its potential. One main obstacles that need be overcome is the─oftentimes─low quality Sn-Pb perovskite films, largely caused by facile oxidation Sn(II) Sn(IV), as well difficult-to-control film crystallization dynamics. Additional detrimental imperfections introduced thin film, particularly at vulnerable surfaces, including top and bottom interfaces grain boundaries. Due these issues, resultant device distinctly far lower than theoretically achievable maximum efficiency. Robust modifications improvements surfaces films therefore critical advancement field. This Review describes origins covers efforts made so toward reaching better understanding perovskites, particular respect surface improved stability cells. In addition, we also outline important issues integrating subcells achieving reliable efficient double- multi-junction tandems. Future work should focus on characterization visualization specific defects, tracking evolution under different external stimuli, guiding turn processing stable cell devices.

Abstract At present, one of the major factors limiting further improvement inverted (p‐i‐n) perovskite solar cells (PSCs) is trap‐assisted non‐radiative recombination at perovskite/electron transporting layer (ETL) interface. Surface passivation with organic ammonium salt a powerful strategy to improve performance PSCs. Herein, an effective method by using propylamine hydroiodide (PAI) and 1,3‐diaminopropane dihydroiodide (PDADI) reported modify perovskite/ETL These two salts do not form new but directly passivate defects on surface after annealing. The results show that PDADI‐modified films possess lower defect density less as well improved charge carrier transport. Based this strategy, p‐i‐n PSCs deliver impressive efficiency 25.09% (certified 24.58%) open‐circuit voltage 1.184 V. Furthermore, unencapsulated also exhibit good storage stability, retaining 91% initial PCE 65 °C in N 2 glove box for 1300 h. This provides efficient route fabricate highly stable structured

Abstract To elevate the performance and durability of perovskite solar cells, a holistic approach to mitigating defects throughout device is essential. While advancements in refining top interfaces have been significant, potential stabilizing buried grain boundaries has not fully tapped. The research underscores transformative impact guanidine phosphate (GP), chemical agent that converts surplus PbI 2 into low‐dimensional perovskite, thus reinforcing stability both boundaries. Employing GP on quantum dot tin dioxide (QD‐SnO ) surfaces revealed an exceptional wrapping effect at these critical junctures, as by high‐resolution transmission electron microscopy. This novel enveloping strategy only passivates but also delays cooling hot carriers, thereby diminishing charge carrier recombination. exhibits enhanced power conversion efficiency, rising from 23.16% 24.55%. Moreover, modified sustains over 90% their initial efficiency after 1000 h maximum point tracking under one sun illumination maintain 1400 moderate humidity, all achieved without encapsulation. breakthrough points robust method for augmenting cell, promising more durable, efficient energy.

Abstract In perovskite solar cells (PSCs), the inherent defects of film and random distribution excess lead iodide (PbI 2 ) prevent improvement efficiency stability. Herein, natural cellulose is used as raw material to design a series derivatives for crystallization engineering. The cationic derivative C-Im-CN with cyano-imidazolium (Im-CN) cation chloride anion prominently promotes process, grain growth, directional orientation perovskite. Meanwhile, PbI transferred surface grains or formed plate-like crystallites in local domains. These effects result suppressing defect formation, decreasing boundaries, enhancing carrier extraction, inhibiting non-radiative recombination, dramatically prolonging lifetimes. Thus, PSCs exhibit high power conversion 24.71%. Moreover, has multiple interaction sites polymer skeleton, so unencapsulated maintain above 91.3% their initial efficiencies after 3000 h continuous operation conventional air atmosphere have good stability under humidity conditions. utilization biopolymers excellent structure-designability manage opens state-of-the-art avenue manufacturing improving PSCs."Image missing"

The conformal and scalable growth of perovskite film on industrially textured silicon with a hybrid evaporation-solution method contributes to sufficient light utilization large-scale commercialization monolithic perovskite/silicon tandem solar cells. However, the efficacy this approach is hindered by incomplete reaction during transition from spin-coating blade-coating techniques, notably involving buried sublimation-PbI2. Herein, we demonstrate triple-source coevaporation (PbI2, PbCl2, CsBr) combined framework-heat-treatment (FHT) strategy. Such inorganic framework composition engineering generates quasi-two-dimensional layered structure, CsPb2X5, which enlarges interlayer spacing facilitates penetration organic salt solution. Consequently, high-quality fully converted PbI2 has been achieved. This advance translates into one best cells that stabilized efficiency 28.3% (1.05 cm2). Impressively, encapsulated device retains 94% its initial performance after operating for more than 1200 h under 1-sun illumination in ambient air.
