Does backsheet delamination affect the optical performance of PV modules?

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.
