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.
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.
Simple mechanical and thermal processing are sufficient to separate the different layers. Furthermore, it provides an optional chemical processing for fine recovery back EVA and solar cells. The extent of recovery of the PV module can be chosen based on the level of process sophistication.
In contrast, this study explores the separation of the back metallization of solar cells, enabling the removal of the back EVA and backsheet before thermal treatment. This approach, in contrast to conventional thermal treatment, eliminates the generation of hydrofluoric acid and fluoride byproducts from the backsheet.
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.
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 [ , , ].

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.
Organic–inorganic hybrid perovskite solar cells (PSCs) have emerged as one of the most attractive next-generation photovoltaic technology in recent years. In 2009, methylammonium lead trihalides perovskites were first employed as sensitizers in dye-sensitized solar cells, yielding an efficiency of 3.8%.
The disassembly of an apoptotic cell into subcellular fragments, termed apoptotic bodies (ApoBDs), is a hallmark of apoptosis. Although the generation of ApoBDs is generally understood as being stochastic, it is becoming increasingly clear that ApoBD formation is a highly regulated process involving distinct morphological steps and molecular factors. …
