Photovoltaic module glass removal

In this study, we present a rapid delamination strategy for recycling EoL photovoltaic modules, enabling the direct recovery of components including solar cells, glass, fluorine-containing backsheets, and ethylene–vinyl acetate film. This approach leverages the varying thermal expansion properties of each panel layer.

Recovery ratio of over 98% for both tempered glass and solar cells. The recycling of end-of-life (EoL) photovoltaic modules represents the final step in the photovoltaic industry chain. A critical prerequisite for component separation and recovery is the delamination of the solar panel layers.

PV modules contain tempered glass, adhesive films, and valuable metals such as silver, aluminum, silicon, lead, and tin, making their recycling both environmentally and economically worthwhile. Economic benefit analyses indicate that recycling each 1 kW module can yield a return of $25.68 .

After heating the PV panel with a microwave, the results showed that removing the glass pane could be conveniently conducted easier than a non-heated panel by about 50-60% of the force. In summary, the microwave frequency appeared to be an attractive option for delaminating expired or damaged PV panels.

approach allowed for easy separation of broken glass from the PV panel. As a result, significantly increasing the integrity of the solar cell. This will also allow for the thorough removal of all glass parts from the sample surface, as well as testing the effect of microwave heating on the delamination of the remaining pa nel. silicon PV panel.

well as testing the effect of microwave heating on the delamination of the remaining pa nel. silicon PV panel. The findings revealed that the temperature had a significant impact on the separation of glass shards from the solar panel's EVA layer. Microwaves' dielectric heat property involved heating electrically
