Currently, PV recycling mainly involves two steps: disassembly and purification. Although there are thousands of models of Si PV panels, they generally share the same basic design. The sandwich structure solar cells, composed of aluminum, silicon and silver, are connected into modules by copper wires sol-dered with Pb and Sn.

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.
As early as 2012, the latest revision of the EU Waste Electrical and Electronic Products Management Regulations took the lead in bringing solar PV modules into the scope of management. Solar cells are officially classified as electronic waste and require efficient recycling [24, 25].
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.
In cases of intact modules, the cover glass can be readily separated from the solar cells after the decomposition of the bonding materials. However, when dealing with damaged modules, the glass and solar cells are typically mixed in granular form, posing a considerable challenge for separation.
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.

Photos of disassembling the solar cell valve. Self-assembled monolayers (SAMs) are widely employed as effective hole-selective layers (HSLs) in inverted perovskite solar cells (PSCs). However, most SAM molecules are amphiphilic in nature and tend to form micelles in the commonly used alcoholic processing solvents. This introduces an extra ...
