There are many types of solar cells, including silicon solar cells, multi-compound thin-film solar cells, polymer multilayer modified electrode solar cells and nanocrystalline solar cells, among which silicon solar cells are the most mature and dominant [11, 12].At present, silicon is the dominant material for solar cells and solar cells made of silicon materials include: …
The solar cell layer is sandwiched between the cover glass and the backsheet material, they are encapsulated by ethylene-vinyl acetate (EVA) and protected by an aluminum frame. The removal of EVA is a necessary prerequisite for the recycling of waste solar modules.
The removal of EVA is a necessary prerequisite for the recycling of waste solar modules. And solar cells are recognized as the most valuable materials for recycling among modules. The direct recovery of intact solar cells and the cover glass is considered the more suitable method [ , , ].
This work aims at the efficient liberation and separation of glass particles and solar cells from damaged waste PV modules. Two common liberation techniques, pyrolysis, and mechanical crushing, were applied. They were contrasted in terms of product particle size distribution and characteristics.
Reasonable and efficient recycling of waste crystalline silicon (c-Si) photovoltaic (PV) modules benefits environmental protection and resource conservation. The liberation and separation of solar cells in modules is the key to achieving effective recycling.
However, when dealing with damaged modules, the glass and solar cells are typically mixed in granular form, posing a considerable challenge for separation. The separation of glass and solar cells is the premise of recovering silicon, silver, and other valuable materials.
And the recovery and concentration of the solar cells can be further improved by optimizing. Firstly, the narrow-grade classification is an important method in improving the recovery and concentration of solar cells. It can be achieved by customizing special mesh sizes.

After disassembly of the Al frame, junction box and cables, the module is a "glass-EVA-solar cell -EVA-backsheet" sandwich structure. Disposal technologies for surplus components can be divided into three forms: upcycling (i.e. high-value recycling), recycling (i.e. medium-value recycling) and downcycling (i.e. low value recycling) [ 4 ].

The liberation and separation of solar cells in modules is the key to achieving effective recycling. The recovery of intact waste modules has been studied by some scholars, but few have specifically examined damaged modules. This study focused on modules that have been broken during transportation, installation, use, or disassembly. Two liberation methods, …
The report recommends using PET-based or bio-based materials for the backsheet instead of fluorinated polymers, to avoid the release harmful gases during processing. Additionally, it suggests substituting adhesives in the frame with O-rings or U-profiles to facilitate module disassembly without damaging other components [61].
