Abstract Metal halide perovskites are of great interest for application in semitransparent solar cells due to their tunable bandgap and high performance. However, fabricating high‐efficiency perovskite devices with average visible transmittance (AVT) is challenging because absorption coefficient. Here, a co‐evaporation process adopted fabricate ultra‐thin CsPbI 3 films. The smooth surface orientated crystal growth the evaporated films make it possible achieve 10 nm thin compact continuous morphology without pinholes. When integrated into p‐i‐n device structure glass/ITO/PTAA/perovskite/PCBM/BCP/Al/Ag an optimized transparent electrode, these layers result impressive open‐circuit voltage (V OC ) 1.08 V fill factor (FF) 80%. Consequently, power conversion efficiency (PCE) 3.6% AVT above 50% demonstrated, which first report active layer thickness , FF AVT. These findings demonstrate that deposition by thermal evaporation makes form films, future smart windows, light‐emitting diodes, tandem applications.

Due to their excellent thermal stability and ideal bandgap, metal halide inorganic perovskite based solar cells (PSCs) with inverted structure are considered as an choice for perovskite/silicon tandem cells. However, the power conversion efficiency (PCE) of still lags far behind that conventional n-i-p PSCs due interfacial energy level mismatch high nonradiative charge recombination. Herein, performance is significantly improved by engineering CsPbI3-x Brx films 2-mercapto-1-methylimidazole (MMI). It found mercapto group can preferably react undercoordinated Pb2+ from forming Pb-S bonds, which appreciably reduces surface trap density. Moreover, MMI modification results in a better alignment electron-transporting material, promoting carrier transfer reducing voltage deficit. The above combination open-circuit enhancement 120 mV, yielding champion PCE 20.6% 0.09 cm2 area 17.3% 1 area. Furthermore, ambient, operational heat stabilities also greatly improved. work demonstrates simple but effective approach fabricating highly efficient stable PSCs.

Inorganic perovskite solar cells (IPSCs) have garnered attention in tandem (TSCs) due to their suitable bandgap and impressive thermal stability. However, the efficiency of inverted IPSCs has been limited by high trap density on top surface inorganic film. Herein, a method for fabricating efficient reconfiguring properties CsPbI2.85 Br0.15 film with 2-amino-5-bromobenzamide (ABA) is developed. This modification not only exhibits synergistic coordination carbonyl (C=O) amino (NH2 ) groups uncoordinated Pb2+ , but also Br fills halide vacancies suppresses formation Pb0 effectively passivating defective surface. As result, champion 20.38%, highest reported date achieved. Furthermore, successful fabrication p-i-n type monolithic perovskite/silicon TSCs an 25.31% first time demonstrated. Crucially, unencapsulated ABA-treated shows enhanced photostability, retaining 80.33% its initial after 270 h, stability (maintain 85.98% 300 h at 65 °C). The retains 92.59% 200 under continuous illumination ambient air.

Inverted CsPbI3 commonly exhibits a more p-type surface than bulk, which induces severe interfacial recombination and, thus, limits the device's Voc and efficiency in inverted perovskite solar cells (PSCs). Here, gradual CsPbI3/PbS heterojunction is constructed to inhibit such through situ chemical sulfidation with N,N′-diphenylthiourea (DPhTA). DPhTA can directly react form PbS induce p- n-type transition at surface, leads energy level bending downward establishing top of region. PSCs exhibit high 1.20 V reach over 20% (stabilized 19.5%), among highest efficiencies PSCs. In addition, strong Pb–S bond well-matched crystal lattice will protect stabilize layer beneath, thereby greatly improving stability. Resulting retain 95% initial whether after maximum power point (MPP) tracking for 1200 h or N2 storage 300 days.

Abstract Heterojunction perovskite solar cells combine the stability of 2D perovskites and high efficiency 3D perovskites, making them an excellent photovoltaic candidate. While heterojunctions with intermixed or gradient can reduce surface recombination, aggregation phase distribution induce transport losses, thereby limiting device fill factors. Accordingly, a bulk in situ reconstruction (BISR) strategy is proposed to on minim self‐assembled crystal seed, forming heterojunction that runs through entire active layer. This facilitates charge extraction, relieves tensile stress, avoids decomposition grain boundaries. As result, best‐performing show high‐power conversion (PCE) 24.06% 82.9% FF for small‐area (0.105 cm 2 ) superior PCE 19.2% large‐area module (5 × 5 ). Importantly, unencapsulated shows dramatically improved operational stability, maintaining 87% its initial after 8000 h storage under ambient atmosphere at room temperature. work provides effective simple approach establish simultaneously boost PSCs.
