This degradation is exacerbated if the layers of the solar cell are not sufficiently laminated. ... ... For example, electromigration in metal fingers of solar cells may cause an increase in the temperature of affected areas. As a result, encapsulant material may deteriorate, causing delamination failure .
The adhesion between the encapsulation material of the solar cells (EVA) and the backsheet (PET) was ten times higher than the adhesion in the backsheet films. Hence, for the investigated laminates a delamination within the backsheet material may be more likely than delamination between backsheet material and EVA solar cells encapsulation material.
The results showed that 100 % delamination over the cell surface can lead to up to 36 % loss in P max in a solar cell, which can cause significant mismatch losses at the module level. Further, delamination can catalyse other degradation modes by providing paths for moisture ingression.
Wohlgemuth et al. have reported delamination between PET and PVF layers in the modules exposed under climatic conditions in Arizona, USA. Herein, the outer layer (usually PVF) exposed to UV radiation, temperature, ammonia vapour, and moisture underwent degradation becoming brittle and developed cracks .
Gambogi et al. have observed delamination in the outer layer of the PET and PVF-based backsheet in the vicinity of interconnect ribbon in PV modules within five years of operation under external environmental conditions as shown in Fig. 15 (a).
Previous research work on delamination phenomena of PV encapsulation materials dealt solely with the characterization of EVA/glass and EVA/backsheet interfaces. However, delamination within the backsheet material may significantly contribute to the initial failure of PV encapsulation.
