This study focuses on developing cost-effective thermal composites by incorporating ternary eutectic (T.E) salt hydrates into chemically treated diatomite (D.T) via the vacuum impregnation method to create shape-stabilized phase change materials (ss-PCMs). The microstructures, chemical stabilities, thermal properties, and reliability of the composites were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and differential scanning calorimetry (DSC).

Notably, the T.E2/D.T composite demonstrated a high salt loading efficiency of approximately 68 %, indicating that the treated diatomite has the capacity to encapsulate a substantial amount of PCM.

In contrast in the proposed approach, the EVA adhesive is softened by controlled heat so that it can be detached from the PV module structure with gentle mechanical force. The results show that the developed process is effective. In less than 1 min, the EVA layer was separated and recovered with a success rate of over 99 % without damaging the integrity of the recovered EVA and adjacent cells. The used analytical characterization through FTIR, TGA, XRD, and SEM-EDS further confirms the structural and chemical integrity of the recovered materials. Additionally, the method enables direct recovery of valuable copper ribbons at 50 % of the panel’s copper content, and facilitates the subsequent release of clean glass and silicon components after a short heat treatment at 400 °C, a significant improvement over existing techniques. The significance of this process lies in the following two advantages: environmentally, it reduces pollution by preventing the depletion of polymer materials and the release of hazardous gases during polymer degradation; economically, it opens up the possibility of reusing EVA polymer components, recovering intact solar cells, glass and copper ribbons, which improves the sustainability of both solar cell production and recycling processes.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"294 ","pages":"Article 113924"},"PeriodicalIF":6.3,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144912520","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}
