Most often, however, molten salt nanofluids suffer from poor dispersion stability and tend to aggregate, which is challenging to solve with conventional stabilization approaches. In this work, we report the preparation of crumpled hybrid SiO<sub>2</sub>@CrGO particles that are self-dispersible within molten salts for direct absorption-based medium-temperature solar-thermal energy harvesting. The crumpled hybrid SiO<sub>2</sub>@CrGO particles were synthesized through attaching SiO<sub>2</sub> nanoparticles onto GO sheets with silane coupling agents followed by a one-step aerosol drying process. By controlling the loading of SiO<sub>2</sub> particles, the hybrid SiO<sub>2</sub>@CrGO particles possess crumpled rough surface structure and an appropriate density matching with the molten salt fluids. Such features simultaneously suppress interparticle van der Waals attraction and gravitational sedimentation or buoyancy-induced floating, which in turn enable stable homogeneous dispersion of the nanofluids after continuous heating at 200 °C for 30 days and concentrated solar illumination. In comparison with neat molten salts, the SiO<sub>2</sub>@CrGO nanofluids have demonstrated long-term stable uniform dispersion, significantly increased solar absorptance, slightly enhanced specific heat capacity and largely same solid-liquid phase change behavior, which enabled consistent direct absorption of concentrated solar illumination as renewable heat at 200 °C. It is expected that this work provides a facile and effective strategy to overcome the long-lasting dispersion stability issue of molten salt nanofluids and stimulate their diverse applications.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"279 ","pages":"Article 113272"},"PeriodicalIF":6.3,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662676","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}

Recovery of silver from waste solar panels is of particular interest as silver is a fast depleting and valuable resource. In this work, c-Si EoL panels were collected and post removal of junction box and aluminium frames, the laminates were shredded to obtain required size grading. The crushed material was sieved and segregated into five size fractions (F1- F5). Analysis of XRD patterns confirmed presence of metals only in the portion below 300 μm (F4 & F5). The XRF analysis confirmed 0.85 wt% of silver in the metal rich fines (<150 μm). A lab-scale process was developed to recover silver from the metal rich fraction (F5) by leaching with Nitric acid. Acid concentration of 6 M HNO<sub>3</sub>, leaching time 60 min and temperature 60 °C were established as the optimum conditions for complete recovery of silver from the fines. The proposed process for recovery of silver can provide an economic incentive to the solar waste recycling process, as it is focused on fines (comprising of 5 % of the crushed laminates).
