What is the difference between mechanical and thermal treatment of photovoltaic panels?

The mechanical methods include crushing, attrition, and vibration for glass separation and is the less polluting method compared to the other two [ 10, 11, 12 ]. Thermal treatment is mainly used to remove the polymeric fraction of the photovoltaic panel, i.e., EVA resin and backsheet materials [ 13, 14 ].

Can decommissioned PV panels be recycled?

In this context, recycling decommissioned PV panels can be useful to resource recovery of valuable metals while lowering environmental stress. However, the lower share of PV modules and the prolonged life of 25–30 years compared to other waste volumes (e.g., electronic waste) hinder the progress in this direction.

What is thermal delamination of solar panels?

The thermal delamination of PV modules refers to the separation of layers within the solar panels due to heat. This method employs high temperatures to change the properties of the solar modules and break down EVA, enabling the mechanical separation of clean glass and silicon solar cells ( Yu et al., 2022 ). EVA can be decomposited in two stages.
