Herein, a group of experts of the International Energy Agency's Photovoltaic Power Systems Programme Task 13 collect and describ the most important technical KPIs used in the industry. 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. This study demonstrates that the uncertainty in KPI estimation is not well understood and depends on data quality, climatic variability, and system configuration.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 24","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252841","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}

Hence a review in this direction to address various unexplored concerns of these materials particularly, the defects and unfavorable band positions that give rise to enormous nonradiative recombinations, leading to major voltage losses in these devices is necessary. The article also discusses the structural and electronic properties, deposition techniques, device optimization strategies, impact of grain size, interface engineering, cationic disorder, transport layers, and light-harvesting techniques that may be required to enhance the device performance.

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}

Herein, a new alternative for green electricity supply using solar-driven evaporators devices fabricated with hydrogels is described. 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. Automated UVF image analysis and refinements of correlations between different BoMs and UVF pattern geometry can further unlock the potential of UVF as a straightforward tool accessible to all stakeholders and promote proactive strategies for the optimization of the reliability and performance of PV power stations.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 24","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400566","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252746","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 most precise method to determine the current (mis)match of a monolithic dual-junction solar cell is a spectrometric measurement with, e.g., a light-emitting diode (LED)-based solar simulator. However, recoding multiple current voltage curves (IV curves) under different red- and blueshifted spectra relative to the AM1.5g reference spectrum is time-consuming. Herein, a new method is suggested to quickly test solar cells for current mismatch. A solar simulator with two lasers instead of multiple LEDs is used, so that two monitor diodes can track intensity changes of each light source during the measurement. Postmeasurement corrections can be applied using this data, circumventing long stabilization times of the solar simulator. To minimize the scan time, it is focused only on determining the correct short-circuit current and not the full IV curve. The measurement method is validated comparing it to conventional spectrometric measurements using a stable III–V monolithic dual-junction solar cell. The measurement on the proof-of-concept setup shows a deviation of only 2.3% in the current at the current matching point compared to the reference measurement.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"8 24","pages":""},"PeriodicalIF":6.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202400686","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252599","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}
