A solar panel or photovoltaic module is a device that converts solar energy into electricity. To ensure effective energy generation, it is crucial for a PV plant that the functioning of the photovoltaic module is fault-free, or at the very least that the defects can be recognized early.

This paper provides an overview of c-Si solar PV panel assembly and recycling methods, and mainly introduced the module delamination and material recovery. There are three methods of component delamination: thermal, mechanical and chemical delamination.
A key stage of the EOL solar panel recycling is delamination, whereby the junction box, cables, and aluminum frames are removed, and the EVA/cell/backsheet is delaminated, resulting in metal enrichment.
This method leverages the metallization on the back of solar cells to enhance the delamination of PV modules.

Delamination directly impacts the optical, electrical, thermal, mechanical, and structural properties, whereas it indirectly promotes the initiation and propagation of other types of D&Ds in a PV module [, , ].
Multiple studies have examined delamination in PV modules based on their origin [,, ], type [10, 17], operating mechanism [,, ], environmental factors responsible [,, ], and testing techniques [,,,, ].
Backsheet delamination does not have a direct impact on the optical performance of the PV module, however, delamination at the front-side at cell-encapsulant or glass-encapsulant interface can directly impacts the module operation. In this regard, the grey appearance along the front side delamination has been investigated in detail.
Delamination in the field-aged PV modules has been prominently observed on the cells over the junction box or along the busbars within a cell. It can be due to the presence of relatively high operational temperature of the cells along busbars and over junction box owning to thermal barrier to heat flow.
Novel PV module architecture to replace delaminated encapsulant layer can be designed. However, such module architecture would require careful disassembling of the complete module structure such as aluminium frame, junction box, glass, and backsheet layer to remove delaminated encapsulant.
Herein, various accelerated tests sequences specified in IEC standards for terrestrial PV modules in both individual and combined capacity, thermal characterization techniques, as well as fracture mechanics-based methods have prominently been used to examine the chemical and physical mechanisms responsible for delamination.
