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}

Herein, we further enhance the solar evaporation rate by harnessing the abundant ambient heat through exquisite structural design. We demonstrate that Carbonized Ganoderma (CG) exhibits an evaporation rate of 4.9 kg m−2 h−1 with a 94% solar–to–steam efficiency under one sun irradiation. This ultrahigh evaporation is achieved by efficient absorbance of ambient heat, which is significantly larger than solar energy. The CG, characterized by a natural hierarchical microstructure with high specific surface area and permeability, maximizes the utilization of ambient heat. Furthermore, our quantitative analysis reveals that ambient heat plays a dominant role in driving evaporation, especially for such high evaporation rate far exceeding the thermodynamic limit of 1.48 kg m−2 h−1.

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.

This study explores the degradation of the front and rear sides of TOPCon solar cells under different firing temperatures through highly accelerated temperature and humidity stress testing (HAST) and dry thermal stress testing (DST). It reveals that 700°C is the optimal firing temperature to balance efficiency and stability. The degradation was mainly induced by moisture corrosion during testing. The solar cells showed a notable reduction in PCE, with relative decreases of ∼5.89% after HAST testing. The primary cause of degradation is a considerable increase in recombination within the metallized regions, likely due to contact corrosion. The results of mini module-level tests demonstrated that rear-side moisture corrosion was the dominant factor influencing the damp-heat resistance of TOPCon solar cells.

The graphene photothermal conversion (E-GR) membranes were obtained to investigate the effect of electrochemical preparation conditions on the photothermal conversion performance. The evaporation rate of E-GR membrane was 1.267 kg m−2 h−1 under 1 sun, achieving a solar-to-steam conversion efficiency of 79.65%.

During this period, the crystalline salt was formed only at the edges with no obvious crystallization on the surface.

Inverted (p–i–n) cells using NiOX as hole-transport layer (HTL) have gained attention due to their easy fabrication methods and high stability, although they often exhibit reduced efficiencies due to non onlyoptimized energy-level alignment. To address this issue, different approaches have been developed, such as the use of self-assembled monolayers (SAMs) on top of the HTL. Herein, a comparative study between regular p–i–n cells and cells using Me-PACz as an SAM on top of NiOX is we presented. Devices with SAM exhibit enhanced open-circuit voltage and efficiency. Temperature DC and AC characterization reveals that the incorporation of SAM reduces recombination at the interface, as seen from the comparison of the perovskite bandgap (1.6 eV) and carrier activation energy ≈1.1 and ≈1.59 eV for reference and SAM, respectively. Finally, an outdoor degradation experiment with minimodules has been conducted. The experiment spanned for more than 500 days, and results show that minimodules with SAM were less stable than those based on the reference layer structure. This is due to a severe decrease in the short-circuit current, which could be attributed to a deterioration of the SAM spacer.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 13","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500243","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573879","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}
