However, given the surface requirements for photovoltaic development, utilizing water surfaces for floating photovoltaic (FPV) systems presents a promising solution. To enhance the cost-effectiveness of these systems, bifacial modules and tracking systems can be employed. While numerous experimental studies have evaluated the performance of fixed-configuration FPVs, floating tracking configurations remain underexplored. In addition, various simulation tools offer insights into different configurations, but their different assumptions often yield inconsistent results. This study focuses on the experimental evaluation of a horizontal axis tracking bifacial FPV (HT-bFPV) system. Over one year, the HT-bFPV system was monitored at the FPV test bed of “Enel Innovation Hub & Lab” in Catania, Italy. The experimental results were compared with simulated outcomes using two software tools, to assess their precision in calculating the HT-bFPV performances. The results reveal that the module temperature of the HT-bFPV system is 3 °C to 6 °C lower than the temperatures calculated by System Advisor Model and Photovoltaic system software, respectively. The yearly reference yield of 2139 kWh/kW produced a final yield of 1801 kWh/kW. The yearly performance ratio of the HT-bFPV system was 0.86, which improved by 1.8% when adjusted for temperature. The simulation results closely matched the experimental data, validating the system's performance. Furthermore, it was confirmed that the HT-bFPV system can produce up to 13.3% more energy with more potential in sites with higher latitudes compared with a similar fixed system.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 3","pages":"484-491"},"PeriodicalIF":2.5,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860995","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}

Micro-CPV modules utilize direct normal irradiance to convert sunlight into electrical power, necessitating precise solar tracking. The performance of these modules is influenced by their alignment toward the sun and prevailing outdoor conditions during outdoor operation. The spectral conditions, along with the ambient temperature, irradiance, and wind speed, influence the current–voltage characteristics of multijunction solar cells and the optical behavior of the lens. We have developed a novel micro-CPV module concept, which is based on low-cost and high-throughput manufacturing processes. In this work, we present a prototype module in a 10 × 6 array configuration (205-cm2 aperture area, submodule class). We discuss outdoor measurements recorded over one year and the influences of various outdoor conditions. In an IEC62670-3 power rating, efficiencies of 36.0 ± 0.4% and 33.0 ± 0.4% at concentrator standard test conditions and concentrator standard operating conditions, respectively, are determined. Highest efficiencies, about 0.4% higher than at standard conditions, were attained at a more red-rich spectrum, namely at a spectral matching ratio <italic>SMR12 of 0.94 ± 0.03. Using measurements at different temperatures, we show that the planoconvex silicone-on-glass primary lens has a negligible temperature dependence. Changes in the module performance over the course of one year are discussed. Despite employing commercially available low-cost components and high-throughput processes, no significant degradation was observed during the first year of operation.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 3","pages":"434-441"},"PeriodicalIF":2.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10938951","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860921","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}

One way to mitigate this is by using impermeable front- and backsheets, with an edge sealant around the module perimeter. While a suitable sealant should have low bulk permeability, proper sealant application to avoid higher ingress channels at interfaces is crucial. Here, we report on the use of a gravimetric method as a simple way of evaluating moisture ingress through an edge sealant and of identifying application-related issues that lead to increased moisture ingress. The method uses multiple samples that closely mimic the sealant's intended application as part of an FPV design developed by the company Sunlit Sea. Supported by steady-state water vapor transmission rate measurements and finite-element modeling, the method is shown to be capable of determining the order of magnitude of the permeability of two different candidate sealant materials. Moreover, the method detected several application-related sealant failures that were not discernible through visual inspection. Finally, it uncovered potential issues of debonding of one of the sealants in immersion, highlighting a relevant yet understudied stressor for FPV modules.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 3","pages":"442-450"},"PeriodicalIF":2.5,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860812","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 changes the effective material consumption and the associated effective carbon emissions of electricity produced by each solar panel. This article investigates the impact of different photovoltaic (PV) mounting systems on energy yield, material consumption, and carbon emissions, focusing on the key configurations of fixed-tilt (FT), east–west, and single-axis tracking systems. As global PV capacity rapidly expands, understanding the sustainability of these systems is crucial for decarbonizing the electricity sector. We highlight the impact of different mounting systems on yield at different latitudes and demonstrate that the effective material consumption can vary by over 30% in terms of both g/Wp and g/kWh, along with the impact on carbon emissions in terms of both gCO2-eq/Wp and gCO2-eq/kWh. Pathways to reduce the carbon footprint in gCO2-eq/kWh by up to 60% compared with the FT baseline case are also discussed, including incorporating green steel and decarbonized concrete.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 4","pages":"610-620"},"PeriodicalIF":2.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331592","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}

A potential to reduce this cost is to reuse the III–V substrate via acoustic spalling, however this technique can leave a rough surface, hindering subsequent device performance. This research investigates the potential of using metalorganic vapor-phase epitaxy growth as a buffer layer to smooth the surface of acoustically spalled germanium and gallium arsenide (GaAs) substrates for improved III–V photovoltaic cell yield and performance, while retaining the maximum number of reuses of a substrate. Three potential smoothing layers were explored: lightly doped C:GaAs, highly doped Se:GaInP, and lightly doped Se:GaInP. C:GaAs showed the most promise as a smoothing layer, while Se:GaInP tended to conform to the underlying morphology, potentially increasing roughness in some areas.
