To improve the universality and anti-interference characteristic, this aricle proposes a pseudorandom-sequence coded EL (PRC-EL) for PV module inspection under ambient light. In the proposed method, the uncorrelated ambient light is inhibited by an equilibrium sequence, which results in a much higher anti-noise performance for PV inspection. The feasibility of the proposed PRC-EL method is verified mathematically and a prototype system is established in this work. The experimental results show that this method can significantly improve the anti-interference ability of EL detection method. The EL image can be recovered by using a 10 bit industrial camera for outdoor measurements (the peak is 286 <inline-formula><tex-math>$rm {W}/rm {m}^{2}$</tex-math></inline-formula>), the 40.8 <inline-formula><tex-math>$rm {W}/rm {m}^{2}$</tex-math></inline-formula> can be tolerated by a low-cost 8-bit camera, suitable for indoor and cloudy environments. Furthermore, the stable high-quality images can be restored continuously using the adaptive-order PRC-EL method under widely varying ambient light conditions. The proposed method can make full use of daily working hours and conditions to perform nondestructive testing and online detection of PV modules, which expands the number of potential application scenarios for EL methods significantly. The proposed method shows major potential to provide improvements in the detailed regular inspection, classification, and performance research of PV modules.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 2","pages":"332-342"},"PeriodicalIF":2.5,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455251","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 energy-industry systems of the Americas are largely lagging as fossil fuels still dominate the electricity generation mix and the system as a whole. Energy-industry transition pathways are developed for all countries of the Americas reaching 100% renewable energy (RE) by 2050 for all energy and industry sectors. To benchmark the transition to 100% RE, the results are compared to current energy policies across the Americas, representing business-as-usual (BAU) conditions. The results indicate the significant potential to expand RE, especially solar PV, to reach the 100% RE target and fully defossilize each region's economy. The levelized cost of electricity (LCOE) can be reduced from its current level of 71 €/MWh to 24 €/MWh in 2050, and the levelized cost of final energy (LCOFE) sees reductions from 49 to 40 €/MWh from 2020 to 2050. Conversely, under BAU conditions, the LCOE only sees moderate reductions to 43 €/MWh in 2050, and the LCOFE remains relatively stable at 39 €/MWh in 2050. Widespread electrification across energy-industry sectors requires significant expansion of solar PV, which accounts for 78% of all electricity supply, leading to 14.8 TW of installed capacity. Furthermore, e-hydrogen for e-fuels and e-chemicals leads to an electrolyser capacity of 4.3 TW\u0000_el\u0000. The dominating role of solar PV thus indicates that the future Americas energy-industry system can be characterized as a Solar-to-X Economy.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"15 1","pages":"17-23"},"PeriodicalIF":2.5,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10726607","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880276","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}

This study substantiates that polymer encapsulated thin film modules offer significantly low glare levels that are essential for building integrated and transport hub installations. In this work, the glare hazard potential associated with matt ethylene tetrafluoroethylene (ETFE)-based polymer sheet used as the frontsheet for the production of flexible thin amorphous silicon (a-Si) PV modules is studied and compared with standard PV glass used in crystalline silicon (c-Si) PV panels. The specular reflectance extracted from the measured total and diffuse reflectance for an angle of incidence (AOI) of 8\u0000<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>\u0000 and the angular intensity distribution (AID) of specular reflectance measured for AOI ranging from 10\u0000<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>\u0000 to 80\u0000<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>\u0000 are utilized for glare assessment of the frontsheets. The mean value of specular reflectance extracted from the measured total and diffused reflectance is as low as \u0000<inline-formula><tex-math>$&lt; $</tex-math></inline-formula>\u00000.5% for the polymer frontsheet and is \u0000<inline-formula><tex-math>$&gt;$</tex-math></inline-formula>\u00004% for glass. The AID measurements suggest that the reflection from the polymer frontsheet is highly diffusive in nature in contrast to glass and the measured specular reflectance is always close to a magnitude lower than that from glass for all AOI. With the increase in AOI, the specular AID reflectance increases exponentially for glass to become as high as 40%, which is almost 20 times less than that from the polymer frontsheet for an AOI of 80\u0000<inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>\u0000. Further, the c-Si test structure with glass and thin a-Si PV module with matt ETFE-based polymer as frontsheet showed similar specular reflectance trends as that of glass and the polymer frontsheet, respectively.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"14 6","pages":"930-936"},"PeriodicalIF":2.5,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517861","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}

By changing load resistances, the output current can be linearly modified. We have conducted the numerical simulations to validate the concept and discussed effects of load resistance, cell area and light source to output current. Our experiment demonstrated that a sufficiently stable current output can be obtained using different light sources, and inversely linear relationship between the output current and the load resistance was obtained. We anticipate that sufficient photocurrent would be required to stabilize the output current.","PeriodicalId":445,"journal":{"name":"IEEE Journal of Photovoltaics","volume":"14 6","pages":"901-906"},"PeriodicalIF":2.5,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518189","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}
