Herein, 2-ethyl-4-oxo-4,5-dihydrothieno[3,2-d]-pyrimidine-6-carboxylate (EDC) was used in a chemical polishing strategy to modify the interface between the hole transport layer and the perovskite layer. Images from scanning electron microscopy show that after EDC modification, there is reduced residual PbI2 in the perovskite film, concurrently with the formation of large-sized grains. It is observed from ultraviolet–visible (UV–vis) absorption spectrum that the Urbach energy decreases after modification, suggesting that grain boundaries exhibit greater order and a reduced defect density. Consequently, the hysteresis index of EDC-chemically polished devices decreased from 8.27% to 2.44%, and the power conversion efficiency increased from 20.5% to 22.17%. Furthermore, EDC-modified PSCs demonstrated exceptional stability, retaining 83% of their initial conversion efficiency after 2000 h of operation under nitrogen atmosphere. After 160 h of outdoor aging at 75°C, these devices maintained 71.3% of their initial efficiency. This work proposes a viable strategy for reducing residual PbI2 in perovskites to achieve highly efficient and stable perovskite solar cells.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cadmium indium sulfide (CdIn2S4) is a promising photocatalyst due to its high efficiency and ability to absorb sunlight. CdIn2S4 is one of the few semiconductors that can absorb up to 620 nm which represents 21% of the photons in solar illumination. Metal species can enhance the photocatalytic performance of CdIn2S4 through increasing charge separation and acting as catalytic sites for redox reactions. Herein, CdIn2S4 micropyramids/nanosheets were synthesized via a solvothermal synthesis and plasma-treated. Different metal species (atomic/small nanoclusters) were post-added to them via the deposition–precipitation route. The plasma-treated CdIn2S4 achieved an enhanced H2 production rate of 985 μmol g−1 h−1 in the presence of benzylamine under visible light irradiation (λ > 400 nm) compared to untreated CdIn2S4 (667 μmol g−1 h−1). The introduction of Au and Ru species further enhanced the H2 production rate to ~8.1 times (7968 μmol g−1 h−1) and 6.7 times (6632 μmol g−1 h−1), respectively, compared to the plasma-treated CdIn2S4. The plasma-treated Au-CdIn2S4 displayed photocatalytic oxidative coupling of benzylamine into N-benzylidenebenzylamine (a value-added product) with high selectivity >92% at a rate of 1102 μmol g−1 h−1 under visible light irradiation (λ > 400 nm).","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1002/solr.202500933#accessDenialLayout","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional AM0 calibration strategies implicitly treat AM0 as an environmental condition that can be approximated by operating at a specific altitude or by reproducing a target spectrum in laboratory simulators. In this work, AM0 calibration is formulated as a device-dependent, spectrum-driven problem rather than an altitude-defined condition. The broadband solar spectrum (250–2500 nm) is synchronously measured during a near-space balloon flight and combined with a calibrated spectral responsivity function to reconstruct the AM0-equivalent short-circuit current directly from measured spectral deviations, without using altitude alone as a proxy for AM0. Altitude-resolved measurements reveal wavelength-dependent atmospheric effects that persist into the lower stratosphere but influence photovoltaic output only within the device responsivity band. Consequently, spectral deviations outside the active wavelength range do not affect the reconstructed current. A crystalline silicon device is used as a case study to demonstrate that near-space measurements acquired under varying spectral conditions can be reconciled into a consistent AM0-equivalent response. These results demonstrate a spectrum-driven route for AM0-equivalent photovoltaic reconstruction from near-space measurements, with potential extension to tandem and multijunction devices given calibrated spectral responsivity data.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key, often overlooked factor is subcell orientation. While single-junction cells are typically optimized for bottom illumination in pin configuration, tandem applications require illumination through the top transparent electrode. Depending on the illumination direction, performance losses are dominated by nonradiative recombination either at one of the interfaces between the perovskite and transport layers or within the bulk perovskite. Identifying which of these dominates the losses remains challenging. Here, we introduce an experimental method to identify the limiting nonradiative recombination pathway and its position in bifacial PSCs. By illuminating devices from either side with red, blue, and white light, the wavelength-dependent fill factor response is used to probe the different recombination pathways. Extensive drift-diffusion simulations, varying 35 parameters and modeling a wide variety of cells, reveal characteristic fill factor traces associated with four recombination scenarios and show 95% accuracy in identifying the dominant loss mechanism using this method. Finally, the method is applied to a vapor-deposited, bifacial PSC for tandem applications, showing that the electron transport layer-perovskite interface limits the performance of this particular device.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/10.1002/solr.70333#accessDenialLayout","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate these issues, we developed a solid-state electrolyte based on a silica aerogel–potassium acetate composite. This electrolyte exhibits an ionic conductivity of 9.6 × 10−4 S cm−1 and an interfacial double-layer capacitance of 2480 μF cm−2. Its hierarchical meso-macroporous network facilitates the capture and capillary condensation of atmospheric water vapor, which establishes localized aqueous pathways for proton conduction. Integrating this composite electrolyte with a CsPbBr3-based photoactive layer to form an all-solid-state photocathode led to a notable suppression of charge recombination. This effect is attributed to the use of acetate ions as effective hole traps at the solid–solid interface. Consequently, the device achieved a steady-state hydrogen evolution rate of 43.4 μmol h−1 under simulated sunlight (AM 1.5 G), corresponding to a solar-to-hydrogen (STH) conversion efficiency of 0.64%. This performance remained stable, with less than 40% decay, over continuous operation for 100 h, demonstrating the robustness afforded by the solid-state design.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
