The fragility of solar cells and frequent vibrations and impacts experienced by car bodies pose significant risks to the reliability of vehicle-integrated photovoltaics (VIPV). Standard PV module designs use soft resins, such as Ethylen-Vinyl Acetate (EVA), to dampen vibrations; however, these materials are ineffective at the higher vibration frequencies encountered in in-vehicle applications. This study employed a laser Doppler vibrometer (LDV) to nondestructively detect cell vibrations and confirm the resonant frequency of solar cells in VIPV modules. This research aims to determine whether the LDV method can detect the independent vibration motion of a solar cell if the solar cells resonate independently within the module, and whether the resonance frequency is close to the natural resonant frequency of the structure. This study also explored the potential of designing resonance-resistant VIPV modules. These findings indicate that the LDV can detect the resonance of solar cells within the vibration frequency range of car roofs. Owing to the low damping factors, the solar cells vibrate independently of the glass cover, with the vibration energy at resonance reaching up to 20 times the normal level. This mechanical resonance poses a substantial threat to the reliability of the VIPV. The study concluded that while eliminating the source of vibration is impractical, making the structure less susceptible to vibration through design modifications is a viable solution, increasing the natural resonance frequency above 2000 Hz.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"294 ","pages":"Article 113903"},"PeriodicalIF":6.3,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144841526","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}

This study investigates the impact of two industrial fluxes on the reliability under damp heat (DH) conditions of n-type TOPCon solar cells referred to as Sample Group A, B, and C. Two industrially used soldering fluxes, designated as Flux A and Flux B, were applied to unencapsulated cells, followed by DH testing at 100 °C and 95 % relative humidity for 122 h or at 85 °C and 85 % relative humidity for 10 h. Sample A exhibit minimal corrosion regardless of flux type, attributed to their denser Ag structure and lower Al content, which reduced susceptibility to flux infiltration. In contrast, Sample B and C show significant degradation, particularly in the front exposure groups, with the sample C demonstrating severe delamination of the metal contacts. Flux A causes more pronounced corrosion than Flux B, likely due to its higher activator content, greater acid value, and the presence of halogens (undisclosed in the flux specifications). However, it should be noted that the corrosion by Flux B is still substantial. Cross-sectional and top-view analyses revealed extensive corrosion and the formation of Pb crystals, highlighting the corrosive effects of flux residues under DH conditions.

A novel process concept, which was previously demonstrated on silicon heterojunction (SHJ) solar cells has been realized for the first time on perovskite/silicon tandem solar cells (PSTSCs). A thin layer of a so-called valve-metal, in this case titanium or titanium-aluminum, is sputtered onto the TCO layer.

By choice of suitable process conditions and valve-metal layer composition, the refractive index of the resulting layer can be tuned to match the optical requirements of the resulting solar cell. PSTSCs with various valve-metal, TCO and metallization combinations have been investigated, showing that this approach has the potential to yield optically competitive surfaces without using any scarce materials.

Over the past decade, the US has begun domestic tellurium production and reduced import reliance from 95 % to less than 25 %. This shift presents an opportunity to minimize the environmental impact of tellurium production. Tellurium is primarily recovered from copper anode slimes via chemical- or heat-based extraction methods. Previous studies use life cycle assessment to evaluate the environmental impact of tellurium. However, these studies model anode slime treatment using electronic scrap processing data as a proxy, which does not accurately reflect commercial processes, and as a result, offers misleading insights for decision-makers. To address this gap, the current study uses life cycle assessment to estimate the environmental footprint of tellurium production via hydro- and hydro-pyrometallurgical processing in China, Canada, Japan, and USA. This work highlights the effect of the tellurium production method and location on the environmental impact of tellurium and CdTe solar modules. The results show that previous estimates underestimate the carbon footprint of semiconductor-grade tellurium by up to 46 %. The literature also underestimates freshwater toxicity and the abiotic depletion potential of CdTe solar modules by 35 % and 50 %, respectively.
