The extension enables more accurate measurements of bifacial solar cells by analytically decoupling the properties of the background (chuck) and the sample. The additional reflectance on a white background commonly accounts for an increase in short-circuit current density by \u0000<inline-formula><tex-math>${0.5},{text{mA/cm}^{2}}$</tex-math></inline-formula>\u0000 compared with a nonreflective chuck. Also, the extension improves the accuracy of absorption profiles in optical solar cell models, and can further be employed to acquire additional information of simple reflectance measurements. The chuck extension is tested on reflectance measurements with black and white backgrounds, showing that the fitting procedure is more stable in comparison to a model without the extension, with the deviation of the parasitic absorption coefficient \u0000<inline-formula><tex-math>$A_text{ppp}$</tex-math></inline-formula>\u0000 being reduced from up to \u0000<inline-formula><tex-math>${30}{%}$</tex-math></inline-formula>\u0000 to less than \u0000<inline-formula><tex-math>${5}{%}$</tex-math></inline-formula>\u0000. We also propose different sets of free parameters in the general Basore model framework, and evaluate some variants of this landscape regarding fit accuracy for different sets of measurement data. We find that most models require information on reflectance and transmittance to be well constrained. To meet the requirement, we propose reflectance measurements on black and white backgrounds to circumvent an additional transmittance measurement setup. Model fits to this dataset show good agreement with measured transmittance and absorptance spectra, with maximum deviations of \u0000<inline-formula><tex-math>${4}{%}$</tex-math></inline-formula>\u0000 absolute within our samples.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"14 5","pages":"737-744"},"PeriodicalIF":2.5,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968634","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}

In this context, challenges and recommendations for rear irradiance instrumentation are described for three types of bifacial irradiance sensors—horizontal albedometer, backward-facing reference cells (or pyranometer), and bifacial reference module. A year of operating field data for single-axis tracked bifacial and monofacial systems was collected, including periods of high surface albedo due to snow ground cover. If snowy conditions are included, we found that all three methods performed comparably to the monofacial baseline case, but only if rear-measured irradiance is incorporated into the expected energy calculation. The lowest RMS error was obtained by following the draft IEC 61724-2 standard and using a calibrated bifacial reference module for bifacial irradiance resource. If measured rear irradiance is unavailable, field conditions either need to be filtered to avoid variable (snowy) albedo or an albedometer measurement can be used in conjunction with modeled rear irradiance along with the draft IEC procedure. Additional practical factors are described, including the proper placement of rear irradiance sensors and the proper interpretation of IEC 61724-1 bifacial performance ratio calculations.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"14 5","pages":"803-814"},"PeriodicalIF":2.5,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10614655","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864220","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 PV development has extensive space requirements, complicated by the increasing competition for land due to rising population growth and food demand. By installing solar panels on agricultural land, agrivoltaic (APV) offers a resource-efficient solution to the persistent problem of competition for arable lands. This study presents a systematic review of the impact of APV applications on crop yields, agricultural product quality, plant growth microclimate, power generation, human comfort level, economic benefits, and social welfare. In total, 138 APV studies were reviewed in five typical agricultural scenarios, including open-field farming, greenhouse, aquaculture, livestock farming, and forestry, and 34 articles summarized the main metrics for evaluating APV performance. The majority of studies indicate positive impacts of APV on open-field agricultural practices. APV coverage of less than 20% on the greenhouse roof has minimal adverse effects. Livestock farming APV helps reduce heat stress and improve animal welfare. Deploying APV panels in aquaculture fishery mitigates the rise in water temperature and improves water quality. The quantitative analysis and investigation of the impact of APV on agricultural production in this study help develop efficient APV systems worldwide.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"14 5","pages":"705-719"},"PeriodicalIF":2.5,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141864221","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}
