However, interfacial defects and energy losses caused by energy level mismatch hinder the development of efficient inverted inorganic perovskite solar cells (PSCs). To address this issue, a multifunctional small molecule, S‐(2‐aminoethyl) isothiouronium bromide hydrobromide (SPD), which simultaneously achieves chemical and field passivation at the CsPbI2.85Br0.15/electron transport layer (PVK/ETL) interface. SPD contains electron‐donating amino groups (AG) and thiocarbonyl group (TG), enabling strong coordination with undercoordinated Pb2⁺ ions for chemical passivation. In parallel, the cation in this molecule exhibits a significant dipole moment, which modulates the interfacial electric field distribution and thereby suppresses carrier recombination at the interface. Incorporation of SPD at the perovskite surface significantly reduces nonradiative recombination, suppresses hysteresis, and improves carrier extraction. The SPD‐modified inorganic PSCs achieve a champion power conversion efficiency (PCE) of 21.15% with a voltage of 1.268 V, reducing the open‐circuit voltage (VOC) loss to 452 mV.

Due to the defect‐tolerant nature of lead halide perovskites, iQDs can be incorporated within crystal grains without degrading performance, while contributing their unique optoelectronic properties. In this study, silicon quantum dots (SiQDs) are embedded into perovskite films to form high‐quality hybrid thin films. Prior to forming the hybrid film, a femtosecond laser‐based surface engineering (SE) technique is used to fragment SiQDs into highly dispersed, stable, ultrasmall particles (≈2 nm). Incorporation of SE‐treated SiQDs (SE‐SiQDs) into the perovskite layer reduces the density of shallow traps and improves carrier transport. A substantial decrease in residual lead iodide (PbI2) is observed at the film surface, and modulation of the Fermi level is achieved through SiQD incorporation.

Herein, a Brønsted acid pretreatment combined with nitrate anions occupying active sites on NiOx is employed to suppress conventional downward phosphate anchoring and establish an upward phosphate anchoring (UPA) configuration, whereby SAMs anchor not only onto the perovskite layer but also the NiOx surface, effectively bridging hole‐transport in between the interface. This UPA configuration exhibits enhanced interfacial adhesion and improved energy band alignment, while also increasing the surface energy, which promotes perovskite crystallization and facilitates stress release. As a result, the champion PSC achieves an impressive power conversion efficiency of 25.9% with excellent stability. Furthermore, this configuration enhances the suitability of SAMs for large‐area perovskite modules, enabling a 156 × 156 mm2 module to reach a high efficiency of 22.05%.

Here, a simple and effective diagnostic is demonstrated: measuring external quantum efficiency (QE) under varying forward biases. The drift–diffusion simulations reveal that each recombination pathway leaves a distinct bias‐induced signature in the normalized QE: a progressive drop at long wavelengths for back‐limited devices, a short‐wavelength decline for front‐limited devices, and a relatively uniform decrease across all wavelengths for bulk‐limited devices. These predictions are validated with experiments on As‐doped and Cu‐doped CdSeTe devices, with and without passivation layers or different front buffers. In each case, the observed bias‐dependent QE spectral changes align with the simulated recombination map. Because this method uses standard QE instrumentation, it offers a broadly accessible and cost‐efficient means to diagnose recombination pathways—extending beyond CdSeTe to other thin‐film and emerging solar cell technologies. By pinpointing recombination bottlenecks, researchers and manufacturers can strategically refine doping profiles, passivation schemes, and interface designs to further improve device performance.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"26 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PEAI pretreatment of amorphous Sb2S3 films enables [hk1]‐oriented crystallization, full‐dimensional defect passivation (bulk and interfaces), and dual‐interface energy‐level reconstruction via Cd‐I and Sb─I bonding. The PEAI reduces CdS surface energy and preferentially adsorbs on Sb2S3 (211) planes, promoting [hk1] orientation and enhancing carrier transport. Moreover, the penetrated PEAI leads to a 3.7‐fold increase in carrier lifetime, verifying effective defect suppression. The resultant bulk heterojunction (BHJ) solar cells achieve a η of 8.21%, which is the highest efficiency of BHJ Sb2S3 solar cells.

While LiF‐rich SEI layers have been widely studied for their ability to enhance interfacial stability, the contribution of Li2O—a key component in improving ionic conductivity and mechanical robustness—has been largely overlooked. This work tackles this deficiency by developing a cellulose acetate (CA)‐modified electrolyte system, which facilitates the cooperative generation of LiF and Li2O within the SEI layer. Consequently, the CA‐modified poly(ethylene oxide) (PEO)‐based electrolyte enabled exceptional electrochemical stability, ensuring reliable performance under elevated voltages (reaching 4.3 V) and across a wide temperature range (−10 °C–60 °C). Such improvements are ascribed to the synergistic LiF‐Li2O composite SEI layer, which enhances interfacial ion transport and mechanical stability. Furthermore, the scalability of this approach was demonstrated in practical pouch cells, which maintained a discharge capacity of 132 mAh g−1 over 300 cycles at 0.1 C, exhibiting an average Coulombic efficiency of 99.79%.
