High temperature treatment solution for waste photovoltaic panels

What is thermal treatment of Si PV panels?

The thermal treatment of the Si PV panels aims to decompose the EVA adhesive resin and to subsequently separate the main parts of the PVs i.e. glass, silicon cells, metal ribbons-electrodes.

How is photovoltaic waste treated in India?

India recycling regulations: As of now, India lacks specific rules and regulations dedicated to the management of photovoltaic (PV) panel waste, and it is currently treated under general waste regulations (Preet et al., 2023).

Can crystalline silicon photovoltaic (PV) panels be managed beyond recycling?

This research provides a comprehensive analysis of End-of-Life (EoL) management for crystalline silicon photovoltaic (PV) panels, highlighting both challenges and opportunities. The results indicate sustainable options for managing PV panels beyond recycling.

Do photovoltaic panels release hazardous metals during thermal treatment?

The study by explored the metals released into the gas phase and solid residue during a thermal treatment of photovoltaic panels at 600 °C, resembling typical recycling processes. The study identified the release of hazardous metals such as chromium and lead, which raises environmental concerns if proper treatment measures are not implemented.

Can crystalline Si & Ag photovoltaic panels be recovered from end of life?

This work proposes an integrated process flowsheet for the recovery of pure crystalline Si and Ag from end of life (EoL) Si photovoltaic (PV) panels consisting of a primary thermal treatment, followed by downstream hydrometallurgical processes.

Can pyrolysis remove Eva from shredded PV panels?

Next, we examined a pyrolysis treatment of the shredded module with the backing removed by either chemical treatment or cryogenic treatment. Pyrolysis treatment of the PV panel allows for the complete removal of the EVA and therefore liberation of the cell and glass from the EVA.
