Cryogenic Delamination and Sustainability: Analysis of an Innovative Recycling Process for Photovoltaic Crystalline Modules

摘要: The increasing rate of production and diffusion photovoltaic (PV) technologies for industrial domestic applications urges improvement the sustainability their demanufacturing processes in order to reduce amount electronic wastes. Sustainability concerns reduction energy consumption, polluting substances as well effort spent recovery components. There is not an optimal process so far, provided a number different approaches have been devised (see e.g. [1, 2, 3]). A promising choice relies on use thermo-mechanical treatments inducing delamination where interfacial bonding between layers are weakened and, finally, broken separation [4]. In this paper we present preliminary industrialization study, based Finite Element (FE) Analysis, prove validity new sustainable endeavouring process. analysis performed searching thermally induced cycles at cryogenic temperatures. We finally show that it possible induce according specific operating
