In the present work, we combine these methods to analyze the effect of PV module degradation modes on the overall energy generation in a 75 MWp PV power plant. We find that 0.2% of the PV modules are affected by thermal signatures after 5 years of operation and that the thermal signatures lead to a 0.06% reduction in power plant yield. We calculate a payback time of the IRT scan and subsequent replacement of modules affected by thermal signatures of more than 10 years for the investigated power plant. However, the power loss associated with thermal signatures seems to develop nonlinearly over time. This underlines the importance of continuous, long-term monitoring: it enables monitoring of performance in relation to warranty limits and supports prioritization of replacement actions required for cost-effective operations and maintenance strategies. This information is also required to understand PV module degradation modes, their time dependence and their dependence on module technology and climates.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 1","pages":"126-136"},"PeriodicalIF":2.5,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880356","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}

However, the installation of artificial structures on water basins can affect the landscape and raise concerns even among those in favor of renewables. This work specifically investigates the public acceptance of FPV among renewable energy supporters to identify its main drivers and barriers. The investigation was conducted through a public survey, which counted more than 300 respondents favorable to renewable energies. The findings reveal that, while public acceptance of FPV remains positive, it is lower than that experienced by renewable energy systems in general. This disparity is mainly due to concerns surrounding the landscape and fauna impacts of this novel technology. In particular, an inverse relationship between FPV acceptance and its perceived alteration of the landscape beauty is found. Notably, respondents expressing a negative opinion on FPV are also those most concerned by the landscape impact of traditional PV. The investigation also proposes some preliminary solutions for enhancing FPV's social acceptance. The effectiveness of these potential measures is evaluated, providing valuable insights for stakeholders and policymakers in the renewable energy sector.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 1","pages":"191-199"},"PeriodicalIF":2.5,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880358","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 study analyses the accuracy of 15 optical model pairs, using minute input irradiance, to assess POA predictions in a temperate setting by comparing to measured POA for both a tracker and a 55° south-facing tilted system. Using the Mean Absolute error (MAE) of ≤5% as the benchmark, variations were revealed across diverse sky conditions. Model estimates showcased a range of errors, from 2.67% to 51.07%, influenced by condition and system type. For the tracking system, the evaluation showed that in clear conditions, 10 pairs maintained errors within the range. However, this success diminished under intermediate skies, with 5 models remaining within range, and further reduced to 2 models in overcast conditions. The fixed-tilt system demonstrated similar trends but with fewer models meeting the required thresholds; 4 in clear and 2 in intermediate conditions. Only the DISC-SO model pair met the threshold in overcast conditions, exhibiting an MAE of 2.67%. Thus, DISC-SO made it a preferred choice for transposing horizontal irradiance. However, R2 values highlighted challenges due to the high temporal resolution of input data and the hourly data-based SO transposition model. Moreover, the study also examined the impact of decomposition and transposition models on percentage errors. Decomposition changes caused up to 2.43% for tracking systems and 5.34% for fixed-tilt systems. Transposition errors were higher, at 8.53% and 11.51%. Using hourly data reduced errors to 2.35%, 1.44%, and −2.15% in clear, intermediate, and overcast conditions.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 1","pages":"164-172"},"PeriodicalIF":2.5,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880284","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 reviewed the recent studies about the monolithic PSTSCs, emphasizing on the current developments of charge carrier transporting layers over the last years. The potential and merits of new charge transporting materials have been summarized, followed by a short discussion on each part. Self-assembled monolayers present the most evocative prospect by measuring performance experimentally. Based on this kind of materials, the efficiency of tandem solar cells has risen to above 30% with texture surface and other strategies.
