As the demand for more efficient and cost-effective solar technologies grows, innovative materials and designs are explored by researchers to enhance solar cell performance. Herein, the potential of single-walled carbon nanotube (SWCNT) thin films as transparent electrodes in wide-bandgap mixed halide perovskite solar cells is assessed. SWCNTs synthesized by the aerosol chemical deposition method are employed as the back electrode. The transparency of the perovskite cells makes them promising candidates for tandem top cells in a multi-junction solar device. In these experiments, it is demonstrated that perovskite cells with SWCNT electrodes achieve a power conversion efficiency (PCE) of 12.63% in the reverse scan. When combined with a silicon bottom cell (PCE of 22.50%) in a tandem configuration, the overall efficiency reaches 24.37% despite a decrease in the bottom cell's performance due to shadowing effects. In these results, the potential of SWCNT electrodes in developing high-efficiency tandem solar cells is highlighted. In this research, by combining the advantages of perovskite technology with the unique properties of SWCNTs, new avenues for advancing photovoltaic performance and contributing to the broader goal of sustainable energy production are opened.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 2","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117899","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}

Thereby, a set of best practices for reliably handling PV system data is presented and the impact of data quality and climatic variability on KPI calculation is investigated. The effective use of technical KPIs allows triggering data-driven and informed decisions to optimize PV systems and providing a comprehensive overview of how PV systems operate across different conditions and climates. With the worldwide growth of the PV industry, more companies operate/own PV systems in different regions, where the climatic and seasonal profiles differ. This requires context-aware evaluation of KPIs, or the judicious application of multiple KPIs, to ensure that each asset is evaluated correctly. Beyond that, there is untapped potential in the utilization of KPIs through geospatial mapping and extrapolation of fleet KPIs.

The incorporation of attractive designs not only enhances consumer acceptance and marketability but also broadens the applicability of ST-OSCs to windows, facades, and electronic devices. Moreover, aesthetically pleasing solar cells foster a positive, ecofriendly image, driving innovation in renewable energy technologies. This study introduces an effective method for advancing the aesthetic appeal of ST-OSCs through Fabry–Perot microcavity resonance, which increases color saturation by narrowing the transmittance spectrum. A novel Fabry–Perot etalon electrode, consisting of Ag/barium (II) fluoride (BaF2)/Ag, is integrated as a top transparent electrode, achieving both high color purity and high-power conversion efficiency (PCE) in colorful ST-OSCs. By precisely controlling the thickness of the BaF2 layer, a wide color gamut with high color purity is achieved, producing vibrant blue, green, and red hues. The photovoltaic devices were fabricated in ambient conditions, with the blue device exhibiting a PCE of 11.52% and a transmittance peak (T%) of 31.66%, the green device showing a PCE of 11.37% with a T% of 26.66%, and the red device achieving a PCE of 11.29% with a T% of 12.24%.

It is compared with equivalent circuit approaches showcasing the validity and advantages of full device modeling. By combining the simulation of full measurement procedures with C–f and J–V measurements on experimental test structures, the observed C–f characteristics can be quantitatively related to performance losses in scan-time-dependent J–V curves, both originating from ion diffusion. With this combined analysis, insights can be provided on the physical origin and interpretation of the different C–f plateaus caused by the displacement of ions. Finally, the C–f characteristics of PSCs under illumination and the impact of band alignment and recombination at the perovskite interface are investigated. Experimental PSCs with and without electron-transport layer passivation are fabricated, showing a good agreement between the simulated and measured C–f and pointing toward a lower surface recombination for the passivated PSC.

UV-induced degradation (UVID) of nonencapsulated laboratory and industrial solar cells from several manufacturers is investigated. Passivated emitter rear contact (PERC), tunnel oxide passivating contact (TOPCon), and silicon heterojunction (HJT) cells can suffer from severe implied voltage degradation (>20 mV) after UV exposure relating to 3.8 years of module installation in the Negev desert. Front UV-exposure causes more performance loss than an equal rear dose. This is connected to a higher UV transmission of the cell layers outside the bulk, indicating the photons need to reach the silicon surface to induce damage. Current–voltage measurements of the TOPCon groups most sensitive to UV degradation show more than 7%rel efficiency loss with the Voc as the main contributor. For two TOPCon groups, dark storage for 14 days after UV exposure causes an additional voltage drop on a similar scale as the UV damage itself, impeding straightforward reliability testing. UVID appears to be a complex process general to all dominant cell architectures with the potential to diminish efforts in efficiency optimization within only a few years of field employment.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 23","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400628","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868569","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 photothermal electricity production is promoted by alginate-poly(N-isopropylacrylamide) (ALG-PNIPAAm) bio-hydrogel, modified with acid-doped conducting polymer (CP), as thermal absorber component, to minimize energy losses. Direct current and voltage monitoring are used during the solar irradiation experiments to evaluate the power density of the hydrogel thermal electricity generator, whereas electrochemical impedance spectroscopy is employed to approach the diffusion processes. Impedance measurements elucidate the ion diffusion dynamics within the hydrogel, directly correlating this behavior to enhanced power generation. Therefore, the highest power supply (64.4 μW·cm−2) and current stability (32–33 μA), over time, are obtained for ALG-PNIPAAm-PEDOT-PSS hydrogel, demonstrating that hydrophilic groups (OH, SO3H), present in the CP backbone, promote the capillary flow of the electrolyte during the sunlight irradiation. The doped CP molecules facilitate a fast ion transport thanks to a good balance between the material hydrophilicity and the interconnected pores.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 23","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400661","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868568","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}

Such defects can result in high local parasitic current losses, that is, local shunt spots. Depending on the nature of the defects, their geometrical distribution can either be microscopic, for example, induced by texture morphology, or macroscopic, for example, induced by particles during processing. Instead of avoiding the defects themselves, so-called shunt-quenching methods have been proposed to mitigate the associated efficiency loss. This work investigates the following recently suggested methods: 1) a deliberate current mismatch; and 2) engineering the resistive properties of the intermediate layers between the subcells to electrically isolate the shunt. A comprehensive 3D device simulation study is presented to quantitatively analyze the (in)effectiveness of these methods. It is found that shunt-quenching by a deliberate current mismatch can only play a minor role in the overall optimization of the current match point. Engineering the resistive properties of the intermediate layers must be generally considered ineffective. It only works for the rather specific case of strong and macroscopically distributed shunts with little cell-to-cell variation and only if some further requirements of the cell design are met.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 23","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400571","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868566","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}

UVF demonstrates the ability to indicate differences in polymer types and degradation states in backsheets and encapsulation materials of PV modules. The data acquisition rate of UVF measurements is 10 to 15 times higher than that achieved by state-of-the-art near-infrared spectroscopy, enabling the mapping of the bill of materials (BoMs) and degradation state for every module in large PV arrays. Combinations of UVF with vibrational spectroscopies allow the polymer BoMs to be recognized and correlated with aging phenomena such as metal corrosion or potential induced degradation. UVF imaging can also be used for conventional visualization of nonmaterial-related anomalies, such as hot cells or cell cracks. The low purchase cost of the equipment makes UVF an affordable and high-throughput diagnostic method yielding comprehensive information that would otherwise only be accessible by combining several slower and more laborious methods.
