With the emergence of novel OPV materials which can reach up to 20% efficiency, several limitations of ZnO have become apparent. In particular, interactions of the active layer with ZnO under illumination can severely limit the device efficiency and stability. In this study, we investigate how various treatment options of ZnO like thermal annealing, ultraviolet exposure, as well as vacuum treatment can improve ZnO properties. Calcium tests show the release of reactive components form ZnO, and space charge limited current measurements allow to model energy level alignment using drift diffusion simulations. Crucially, permanent Jsc losses related to insufficient treatment of ZnO are observed for high performing material systems. An additional UV treatment step under vacuum is shown to significantly reduce those Jsc losses and allows using ZnO annealing temperatures of only 80°C.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 16","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500156","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905330","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}

The key factor behind these latest breakthroughs is the use of tin oxide as an electron transport layer, which enhances device performance by effectively controlling the extraction, transport, and recombination of charges. However, the performance of perovskite devices is affected by issues such as energy level mismatch and numerous interface defects at the tin oxide electron transport layer/perovskite interface. To address these issues, researchers have optimized the electron transport layer/perovskite interface using different materials. Among them, the material with bidirectional passivation effect, namely bidirectional passivator, has attracted the attention of researchers. This article mainly analyzes the application and prospect of bidirectional passivators at the SnO2/perovskite interface in the n–i–p structure. It can not only passivate the defects of the lower tin oxide layer and reduce the agglomeration of SnO2 crystals, but also improve the growth of the upper perovskite and passivate the defects of the perovskite layer, thereby optimizing the interface contact of SnO2/perovskite and significantly improving the photoelectric performance of the device. The bidirectional passivators are classified into three categories, inorganic salts, acid radical salts, and amino organic compounds, and the mechanism of their bidirectional passivation effect on the SnO2/perovskite interface is elaborated in detail in this paper. Finally, the further development and challenges of bidirectional passivators are discussed.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 17","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022399","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}

Compared to the nontreated devices, the devices incorporating VIDAI demonstrated improvements in power conversion efficiency (PCE) under 1 sun illumination from 15.1% to 16.8% and 17.0% for CN and DIO, respectively, and for indoor illumination from 13.2% to 14.9% and 15.0% for CN and DIO, respectively. This is attributed to optimized surface tension and improved recombination lifetime. Additionally, the VIDAI method enhanced device stability, with the DIO-treated device exhibiting the highest maximum power point stability.

Epitaxially grown c-Si wafers (EpiWafers) detached from reusable substrates allow a significant reduction of this energy consumption. In this work, we studied the suitability of these EpiWafers with tunnel oxide passivating contact (TOPCon) solar cells—the mainstream technology—with a special focus on high temperature stability in the range of 1000°C, as required for the boron emitter diffusion. Small area TOPCon solar cells made of n-type EpiWafers achieved an efficiency of up to 23.4%, which represents the highest value reported yet for EpiWafers exposed to high temperatures. A detailed electronic quality analysis of n-type and p-type EpiWafers does not indicate a degradation after the high temperature steps. The efficiency potential is demonstrated with TOPCon solar cells fabricated on epitaxially grown reference wafers, which achieved efficiencies of up to 24.4% and 24.7% for n-type and p-type wafer polarity, respectively. These results closely match those of solar cells fabricated in parallel on high-quality FZ wafers, showcasing the excellent material quality and high temperature stability of epitaxially grown wafers.

While corrective and preventive maintenance have seen significant progress, the development of predictive analytics that proactively generate warnings to anticipate underperformance issues and potential failures remains underexplored. This article makes a substantial contribution by providing a comprehensive review of maintenance approaches, including corrective, preventive, predictive, and extraordinary, with a special focus on the integration of predictive analytics for smart maintenance in PV systems. The study evaluates how cutting-edge technologies, such as the Internet of Things (IoT) and Artificial Intelligence (AI), facilitate real-time monitoring, diagnostics, and automated early warning systems to anticipate underperformance issues and potential failures, thereby enabling proactive maintenance scheduling. By summarizing the capabilities of these intelligent monitoring systems, the article demonstrates how predictive analytics can significantly reduce unexpected downtime, enhance decision-making, and ultimately lower the levelized cost of energy (LCOE) of PV assets. Finally, the article provides recommendations and outlines future directions for the development of standardized frameworks to optimize smart maintenance practices and improve solar asset management, advancing the state-of-the-art in predictive analytics for the PV industry.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 16","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500289","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905355","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}

The incorporation of RP into g-C3N4 has been shown to reduce its bandgap, thereby enhancing visible light absorption and improving light-harvesting efficiency. The doping of RP into g-C3N4 introduces localized electronic states within the g-C3N4 bandgap and facilitating efficient charge separation. As a result, the modified g-C3N4 exhibits enhanced light absorption and superior photocatalytic activity. At the same time, nitrogen doping in ZnO modifies its electronic structure, enhancing charge transport and suppressing recombination losses. The synergy between RP-doped g-C3N4 and NZnO creates an efficient heterojunction that enables seamless charge transfer and enhances photocatalytic performance. The resulting NZnO-PCN composite has a high specific surface area of 165.6 m2 g−1, which maximizes dye adsorption and interaction, further enhancing device performance. The optimized photoanode exhibits a power conversion efficiency of 8.8%, accompanied by a short-circuit current density (Jsc) of 20.50 mA cm−2, an open-circuit voltage (Voc) of 0.67 V, and a fill factor of 0.64.
