This study investigates the effects of guanidinium halide (GuaX, where X = I, Br, or Cl) surface treatments on PSC performance and stability, addressing challenges related to ion migration and grain boundary instability. Low-energy electron microscopy reveals that GuaX treatments modulate the work function, reducing it from ~5.44 eV in untreated films to ~4.96 eV in GuaI-treated films, a change attributed to differences in electronegativity and ionic size. Conductive atomic force microscopy demonstrates improved and uniformed current distribution, particularly in GuaCl-treated films, owing to GuaCl's ability to mitigate surface and grain boundary defects. Current–voltage mapping highlights GuaCl's role in stabilizing charge transport at grain boundaries. Optimized GuaX treatments substantially enhance photovoltaic performance, with GuaCl-treated PSCs achieving a power conversion efficiency of 21.10%, an open-circuit voltage of 1.15 V, and a fill factor of 80.16%. Surface photovoltage analysis further confirms a significant reduction in trap-state density (from 29–16 meV), while density functional theory calculations indicate that GuaCl exhibits the highest adsorption energy (−2.58 eV), indicating strong interaction with the perovskite. Moreover, stability tests under ambient conditions demonstrate exceptional durability, with GuaCl-treated PSCs retaining over 95% of their initial efficiency after 60 days.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 16","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905519","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}

While iodide-based RPPs are well-studied, the crystallization of mixed-halide RPPs remains less explored. Understanding the factors affecting their formation and crystallization are vital for optimizing morphology, phase purity, and orientation, which directly impact device performance. Here, we investigate the crystallization and properties of mixed-halide RPPs (PEA)2FAn−1Pbn(Br1/3I2/3)3n + 1 (PEA = C6H5(CH2)2NH3+ and FA = CH(NH2)2+) (n = 1, 5, 10) using DMSO ((CH3)2SO) or NMP (OC4H6NCH3) as cosolvents and MACl (MA = CH3NH3+) as an additive. For the first time, the presence of planar defects in RPPs is directly observed by in situ grazing-incidence wide-angle X-ray scattering (GIWAXS) and confirmed through the simulation of the patterns that matched the experimental. GIWAXS data also reveals that DMSO promotes higher crystallinity and vertical orientation, while MACl enhances crystal quality but increases halide segregation, shown here by nano X-ray fluorescence (nano-XRF) experiments. For low-n RPPs, orientation is crucial for solar cell efficiency, but its impact decreases with increasing n. Our findings provide insights into optimizing mixed-halide RPPs, guiding strategies to improve crystallization, phase control, and orientation for better performance not only in solar cells but also in other potential optoelectronic devices.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688201","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}

DSSCs using [Co(bpy)3]2+/3+ redox mediators often face stability challenges due to light–induced interaction with tert-butylpyridine (TBP), an electrolyte additive. This leads to the loss of electrochemically active mediators and degradation of the photovoltaic performance. However, the monolithic DSSCs in this work demonstrate unprecedented stability under continuous light soaking for over 1000 h. The stability is attributed to the device architecture and the carbon CE, which mitigate critical degradation mechanisms. Additionally, its adsorption capacity and opacity reduce the amount of free TBP in the electrolyte, thereby suppressing harmful photoinduced [Co(bpy)3]³+-TBP complexation and water-induced redox reactions. Despite high TBP concentrations (1.2 M), which typically accelerate degradation in conventional DSSCs, the monolithic devices maintained their performance due to electrolyte retention and reduced ion diffusion within the porous carbon layer. This study highlights the critical role of architecture in stabilizing cobalt-mediated DSSCs, paving the way for robust, long-term energy conversion applications.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688202","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}

Electricity, typically generated by burning fossil fuels, remains essential but is also a major source of environmental harm. Hydrogen presents a promising alternative energy vector, capable of replacing traditional electricity generation methods and serving as an efficient energy storage medium. Among available technologies, water electrolyzers are among the most competitive systems for hydrogen production, as they emit no harmful pollutants during operation. However, hydrogen production requires energy input, and renewable sources particularly solar power offer one of the cleanest pathways for this purpose. Like other renewables, solar energy is intermittent, and such fluctuations can affect the stability and efficiency of hydrogen production systems. Directly coupling solar PV with electrolyzers offers potential cost benefits by eliminating converters and reducing conversion losses, but it also presents challenges in terms of system stability and the long-term durability of the electrolyzer. Currently, beyond conventional ground-mounted systems, alternative photovoltaic (PV) configurations are gaining attention, including floating PV (FPV), agrivoltaic PV, and building-integrated PV systems. FPV, in particular, is gaining momentum due to its close proximity to water sources, which facilitates integration with electrolyzers. Offshore FPV systems can be potential by supporting solar-powered desalination to purify seawater for electrolysis. At the gigawatt scale or above of solar-powered hydrogen production, several challenges emerge, including land use constraints, high material costs, and limited availability of resources. While electrolyzer durability is generally well understood, their long-term performance under fluctuating solar input whether through direct or indirect coupling remains under-researched, representing a significant gap in the current body of knowledge.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688198","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}

In this study, we present a novel approach that employs conductive porous overlayers, specifically multi-walled carbon nanotube (MWCNT) films, to facilitate the fabrication of HTM layers. By integrating MWCNT films with HTM precursor solutions, we achieved the simultaneous formation of the HTM layer and the top electrode. Furthermore, selecting an appropriate additional cover layer allowed us to create an HTM layer characterized by uniform thickness and optimal contact with the MWCNT-based electrode. This innovative method eliminates the need for specialized equipment and enables PSC devices to achieve a power conversion efficiency of 17.58% with good stability. This streamlined approach holds significant promise for enabling large-scale, cost-effective production of high-performance perovskite solar cells while addressing the challenges associated with conventional HTM preparation techniques.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688123","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}

This review emphasizes current advancements in SACs-based catalysts, notably addressing their distinctive electronic structure and enhanced charge separation. The review also discusses the sophisticated characterization methods for the analysis of single-atom-based catalysts, coupled with the computational details elucidating the selectivity and activity of these catalysts for PECWS.

Conventional dielectric materials require vacuum deposition and high-temperature annealing, increasing complexity and cost. This study explores Nonafluorobutane sulfonic acid (C4HF9O3S), a superacid, as a passivation layer for silicon solar cells. Unlike traditional dielectrics, it eliminates the need for vacuum processing or high-temperature annealing while offering excellent passivation. Results show that the superacid forms a self-assembled monolayer on silicon, improving passivation and enabling efficient charge extraction. N-type silicon coated with the superacid achieves an effective lifetime exceeding 8.5 ms, and when combined with Al, it forms an interface with a contact resistivity as low as 5.75 mΩ.cm2. Characterization and density functional theory (DFT) calculations confirm both chemical and field-effect passivation mechanisms, validating the monolayer's superior performance. When integrated into a full solar cell, the Nona layer enhances device performance, yielding a 3.05% absolute efficiency gain compared to the reference cell without Nona.
