Therefore, accurate determination of soiling loss plays a crucial role in predicting PV output and ensuring optimized cleaning schedules. The study focused on measuring soiling loss at a 1.1 MW outdoor testing facility in Louisiana, United States, using a DustIQ device, a commercially available soiling sensor. The maximum soiling loss recorded for DustIQ Sensor 1 was 7.5% on August 27, 2023, during the dry season. The measured data was fitted using the well-established Kimber and HSU models (based on PM<sub>2.5</sub> and PM<sub>10</sub>) by optimizing the least squares error, resulting in observed mean absolute percentage error (MAPE) of approximately 0.82% and 0.78%, respectively. One feature of these models is that it is assumed that the solar panels will be completely cleaned after a rain event that reaches a set threshold limit. However, in-field testing at the site shows that assumption to be flawed, because the soiling ratio did not return to 1 or 100% even after significant rainfall events. To address this, improved versions of the Kimber and HSU models were developed to more accurately represent the recovery of the soiling ratio after rainfall events. The results demonstrated significant improvements, with the modified Kimber models achieving reductions in root mean squared error (RMSE) of 23%, 13%, and 1% compared to the optimized Kimber model, while the modified HSU model exhibited a 12% reduction in RMSE over the optimized HSU model.

Perovskite solar cells (PSCs) that are hybrid (organic–inorganic) have demonstrated remarkable PV ability. The advantages of halide-based perovskite are numerous and include cheap cost, high efficiency, and simplicity in fabrication. Due to their poisonous nature, lead (Pb)-based PSCs often pose a concern to the environment. They also have other drawbacks, such as stability problems, problems with scalability, and health risks associated with Pb exposure. Thus, the primary intent of this study is to examine the Pb-free, inorganic titanium-based perovskite complex Cs<sub>2</sub>TiI<sub>x</sub>Br<sub>6-x</sub>, which serves as the active layer. When compared with other elements, titanium is nontoxic, strong, affordable, and easily accessible. To improve the efficiency of lead-free (Au/CuSbS<sub>2</sub>/Cs<sub>2</sub>TiI<sub>x</sub>Br<sub>6-x</sub>/CdS/FTO) device structure, both linear and parabolic grading methods are used in the simulation. The perovskite composition Cs<sub>2</sub>TiI<sub>x</sub>Br<sub>6-x</sub> is a mixed halide system, with different amounts of iodine (I) and bromine (Br) ions integrated into the crystal lattice. Within the halide system, “x” indicates the percentage of iodide ions that replace bromide ions. Light absorption and energy conversion efficiency in solar cells may be maximized by fine tuning the material's band gap by varying “x,” which can range from 0 to 6. When the active layer is graded linearly, the band gap is adjusted by adjusting the composition <i>x</i>, which ranges from 0 to 6, throughout the active layer's thickness. The bending factor changes from 0 to 1 in the case of parabolic grading of the Cs<sub>2</sub>TiI<sub>x</sub>Br<sub>6-x</sub> layer, indicating an enhancement in the device's PCE as a result of high wavelength photon absorption. Our simulations show a significant improvement in PCE, with an astounding result of 31.18% for parabolic grading, a 7.93% increase above PCE from linear grading, which is 28.89%. Other noteworthy metrics that exhibit exceptional outcomes include J<sub>SC</sub> 34.36 mA.cm<sup>−2</sup>, FF 86.81%, and V<sub>OC</sub> 1.0452 V. The stability in the output of the device in the realistic temperature range confirms the highly stable nature of the proposed PSC device. These results show how effectively our approach improves the efficiency and effectiveness of Pb-free PSC's. As we are interested in this realistic environmental temperature range of the whole world, we proposed that Cs<sub>2</sub>TiI<sub>x</sub>Br<sub>6-x</sub>-based PSCs are highly suitable and stable for the real-time experiment, which is the need of PSCs nowadays.</p>\u0000 </div>","PeriodicalId":223,"journal":{"name":"Progress in Photovoltaics","volume":"33 5","pages":"599-615"},"PeriodicalIF":8.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we explore some of the attractive encapsulation materials in terms of their ability to prevent moisture ingress, withstand elevated temperatures, and have suitable mechanical properties to avoid thermomechanical issues. We utilized the previously suggested concept of the “perovskite test,” an optical test with simple sample fabrication, for evaluating encapsulation quality and validated the findings with the full solar cell stack. Unsurprisingly, encapsulants without an edge sealant showed insufficient protection from moisture. Ionomer in combination with butyl edge seal showed the best barrier properties; however, this stack led to rapid delamination of the cell layers in thermal cycling tests. Configuration with only edge sealant does not have such an issue in principle (no mechanical stress applied), but an absence of the polymer in the stack is unfavorable in terms of optical design and sometimes showed perovskite degradation that we assign to trapped moisture in the butyl itself. Polyolefin with butyl edge sealant is not free of degradation but showed the most promising compromise by passing the damp heat test and showing fewer issues in the thermal cycling experiments.

This opens up vast new scenarios for solar modules and significantly boosts the capacity of renewable energy. To ensure high efficiency and stability of the solar modules, several challenges need to be overcome. Degradation due to elevated temperature and/or humidity is a critical concern for silicon heterojunction (SHJ) solar modules. Here, we investigated the stability and degradation mechanism of encapsulated cells with lightweight configurations where the cells are based on three different types of transparent-conductive oxide (TCO): indium tin oxide (ITO), aluminum-doped zinc oxide (AZO), and a combination of ITO/AZO/ITO under humid and thermal environmental conditions. A damp heat (DH) test at a temperature of 85°C and relative humidity (RH) of 85% was performed on lightweight modules for 1000 h. Our results show that AZO is the most susceptible to DH degradation. The AZO film was damaged by the combined effects of moisture ingress and delamination of the interconnection foil, resulting in a decrease in the conductivity of the AZO film, leading to a dramatic increase in <i>R</i><sub>s</sub> and a decrease in <i>FF</i> of the modules. Consequently, moisture has a greater chance of percolating through the damaged AZO layer into the a-Si:H passivation layer, causing passivation degradation, which leads to an increase in recombination, resulting in a decrease in <i>V</i><sub>oc</sub> of the modules. In particular, after capping the AZO film with an ITO film, the efficiency loss of the ITO/AZO/ITO module was significantly reduced. This suggests that the ITO film could be a promising protective capping layer for the AZO-based solar cells.</p>","PeriodicalId":223,"journal":{"name":"Progress in Photovoltaics","volume":"33 4","pages":"541-550"},"PeriodicalIF":8.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pip.3880","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
