Environmental fatigue crack growth of PV glass/EVA
The delamination of encapsulants in photovoltaic (PV) modules is a common issue that leads to power loss due to optical losses. Encapsulant debonding is usually examined under monotonic loading conditions
6 FAQs about [Photovoltaic panel soft board debonding]
What is a photovoltaic backsheet?
Backsheets constitute the rear side outermost layer of protection for the active components of standard photovoltaic (PV) modules. One typical backsheet type is comprised of an opaque multi-layer laminated polymeric sheet on the rear side of the module. A thicker core layer provides insulating properties and mechanical strength.
Do PVDF backsheets fail prematurely?
PVDF-based backsheets in deployed PV modules have been seen to fail prematurely. Failure here is defined as cracking. Backsheet cracking can not only compromise the module operating power by enabling enhanced ingress of moisture and oxygen, but it also presents an electrical hazard by exposing the high-voltage components.
Why do PVDF modules crack?
In a recent field study conducted by DuPont, 23% of investigated PVDF-containing modules were defective by year 9 of deployment 13. Cracks were seen to form along busbars; however, no clear correlation with a particular climate was found. The mechanisms behind the observed PVDF-based backsheet field cracking are not fully understood.
What polymers are in PVDF backsheets?
To further complicate our understanding of the polymers in backsheets, the PVDF outer layer is a complex material containing pigments and additives, and it is typically blended with acrylic polymers as well [e.g., poly (methyl methacrylate) (PMMA)] 9, 10, 11, 12.
What is PVDF based backsheet?
PVDF-based backsheets currently make up ~ 50% of the world market share 1. PVDF is a semi-crystalline thermoplastic fluoropolymer formed of covalent C–H and C–F bonds. PVDF has high purity, excellent chemical inertness, mechanical abrasion resistance, and UV stability 2, 3.
Can PVDF-based backsheets replicate premature degradation in the field?
The PVDF-based backsheets studied here underwent various single (UV, DH, TC), sequential (MAST), and combined (C-AST) accelerated stress tests with the goal of finding the most suitable test to replicate premature backsheet degradation in the field.
