- ArtykułOtwarty dostępElectrohydraulic fragmentation processing enabling separation and recovery of all components in end-of-life silicon photovoltaic panels(2025) Padhamnath, Pradeep; Nalluri, Srinath; Kuśmierczyk, Filip; Kopyściański, Mateusz; Karbowniczek, Joanna; Leow, Shin Woei; Reindl, ThomasWydział Inżynierii Metali i Informatyki PrzemysłowejThe exponential increased use of PV panels for energy production would also lead to enormous volumes of PV waste that need to be dealt with in an environmentally responsible manner. In this work we present experimental results for recycling crystalline silicon (c-Si) PV panels using recently developed electrohydraulic shock wave-based fragmentation of PV panels. The electrohydraulic fragmentation process allows for the efficient delamination of the modules and subsequent recovery of almost all valuable materials used in the manufacturing of PV panels, without thermally decomposing the polymers and eliminates creation of any toxic or hazardous waste during the process. We study the impact of the type of panel, size of the feed material and process duration on the quantity and quality of material recovered after the process.
- ArtykułOtwarty dostępEffects of asymmetric rolling with tilted material entry on texture and mechanical properties of aluminiumByrska-Wójcik, Dorota Joanna; Ostachowska, Monika; Gibek, Julia; Wierzbanowski, Krzysztof; Wróbel, Mirosław; Błoniarz, Remigiusz; Baczmański, Andrzej; Kopyściański, Mateusz; Kalemba-Rec, IzabelaWydział Inżynierii Metali i Informatyki Przemysłowej AGHAsymmetric rolling texture of aluminium alloy 1050 was examined both experimentally and numerically. The rolling asymmetry was realized using rolls with different diameters rotating with the same angular velocity and by varying inclination of the rolling strip (i.e., the flat and tilted entry of the rolled strip between rolls). The final, 84% reduction in the thickness was obtained after six consecutive rolling passes. Crystallographic texture variation over the rolled bar thickness was determined using X-ray diffraction and predicted using the Finite Element Method combined with two crystalline deformation models (i.e., the elasto-plastic and the elasto-viscoplastic ones). Textures predicted by both models, taking into account all deformation process parameters, are in good agreement with experimental results. The obtained results confirm the effect of texture modifications caused by the shear stress component, resulting in the shifts of selected texture maxima in the orientation space, and explain the observed texture distribution across the sample depth. The novelty of this work consist in examination of the role of the tilted material entry (besides a difference in rolls diameters) in homogenization of texture distribution in multi-pass asymmetric rolling. The rolling geometry process variants, recommended for the technological practice, are indicated.
- ArtykułOtwarty dostępDevelopment of PV panel recycling process enabling complete recyclability of end-of-life silicon photovoltaic panels(2025) Nalluri, Srinath; Kuśmierczyk, Filip; Leow, Shin Woei; Reindl, Thomas; Padhamnath, Pradeep; Kopyściański, Mateusz; Karbowniczek, Joanna; Kozieł, TomaszThe cumulative PV panel waste is expected to reach ≈8 million tonnes by 2030 and ≈ 80 million tonnes by 2050. This presents an opportunity to pursue new avenues in terms of recycling and improving the circularity of the PV panels. In this work we present experimental results for recycling c-Si PV panels using recently developed electrohydraulic shock-wave fragmentation (EHF) of PV panels. The EHF process allows for the recovery of all materials used in the manufacturing of PV panels. We use different types of panels for the recycling process and analyse the material recoverability in each condition. Further, we analyse the effectiveness of chemical treatment in isolating metals from the silicon obtained from recycled c-Si PV panels, providing an opportunity of recovering high quality metal and silicon. The separation process allows for the high-quality material recovery and could potentially improve the economic feasibility of the overall recycling process.
