To CsPbI3 perovskite solar cells, defects from buried interfaces and improper energy band alignment can cause severe carrier recombination hamper further enhancement in efficiency stability. In this work, we develop an situ strategy to reconstruct the interface for n-i-p typed cells. This is derived exchange reaction between 18C6/Cs+ Pb2+, leading formation of 18C6/Pb2+ crystallization process (18C6: 18-crown-6 ether). The as-prepared complex acts as a kind molecular barrier modify TiO2/perovskite passivate under-coordinated Pb2+ iodide vacancies. Additionally, free Br– ions diffuse into lattice film bottom, forming front-surface field suppress recombination. Based on strategy, high 22.14% has been achieved, demonstrating one highest efficiencies cells date. Besides, modified cell maintain 95% its initial after 1500 h MPP testing long-term stability testing, exhibiting excellent operational

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 The complete phase transition from DMAPbI 3 and Cs 4 PbI 6 intermediates to the final CsPbI perovskite is pivotal for fabricating high‐quality inorganic films. In this study, reaction energy barrier between sought be reduced by increasing their surface energy, where a perfluorinated compound designed using DFT modeling saturate of effectively prevent crystalline growth. Consequently, smaller with ultrahigh react more energetically facilitate rapid conversion desired phase. It found that resultant shows improved crystallinity morphology, as demonstrated suppressed non‐radiative recombination prolonged carrier lifetimes. As result, optimized solar cells (PSCs) achieve power efficiency (PCE) over 20%, along significantly light thermal stability. This work provides way regulate crystallization dynamics advanced quality perovskites.

Опубликована: Окт. 24, 2024
Abstract Halide‐related defects at the buried interface not only cause nonradiative recombination, but also seriously impair long‐term stability of perovskite solar cells (PSCs). Herein, a bottom‐up, all‐in‐one modification strategy is proposed by introducing multisite antioxidant ergothioneine (EGT) to manage iodide ions and manipulate crystallization dynamics. The findings demonstrate that EGT passivates uncoordinated Sn 4+ /Pb 2+ defects, firmly anchors inhibits their oxidation I 2 . Additionally, enhances oriented perovskite, improves carrier dynamics, releases residual stresses. Consequently, optimized all‐air processed device (Rb 0.02 (FA 0.95 Cs 0.05 ) 0.98 PbI 2.91 Br 0.03 Cl 0.06 achieves remarkable power conversion efficiency (PCE) 25.13%, which among highest values reported for devices fabricated in air, along with ultrahigh open‐circuit voltage ( V OC 1.191 fill factor (FF) 84.9%. without encapsulation exhibits strong humidity, thermal, operational under ISOS protocol.

Abstract Self‐assembled molecules (SAMs) have been widely employed as hole transport layers (HTLs) in inverted perovskite solar cells (PSCs). However, the carbazole core of [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) is insufficiently effective for passivating defects at “bottom” films, and weak anchoring ability phosphate groups toward NiO x substrate appears to promote formation dimers, trimers, higher‐order oligomers, resulting molecular accumulation. Herein, a novel technique proposed combine Me‐4PACz with different thiol modify buried interface PSCs. Molecular dynamics simulations infrared scattering‐type scanning near‐field optical microscopy (IR s‐SNOM) results show that co‐depositing forms hybrid SAMs densely uniformly cover surface. The island‐like structure serves template forming bulk heterojunction composed interpenetrating networks MA‐rich FA‐rich domains, enabling efficient charge generation suppressed bimolecular recombination. Particularly, (3‐mercaptopropyl) trimethoxysilane (MPTMS) effectively prevents aggregation by multi‐dentate anchor on surface through hydrolytic condensation ─OCH 3 groups, while its ─SH passivate uncoordinated Pb 2+ perovskite/HTL interface. Consequently, SAMs‐modified PSC achieve champion photoelectric conversion efficiency (PCE) 25.4% demonstrated better operational stability.
