What is a PV module?

PV module is a packaged and protected system in which multiple PV cells are connected to deliver the electric power. Generally, PV cells in a PV module may be crystalline, semi-crystalline, or amorphous and they are safely packaged in multiple protective layers including front cover, encapsulate, and back sheet.

Which material is used to encapsulate PV modules?

Ethylene vinyl acetate EVA, a copolymer of ethylene and vinyl acetate is the predominating material of choice for manufacturing the encapsulate film since the early eighties, and nearly 80% of PV modules are encapsulated with EVA film [4, 13, 29].

Why is encapsulation of PV modules important?

Encapsulation of PV modules is one among the multiple ways to mitigate these stability issues and it plays an important role in the enhancement of the device lifetime by providing a barrier structure to restrict the penetration of oxygen and moisture.

What is PV encapsulate?

Generally, the encapsulate is a polymeric film which plays a critical role in avoiding environmental degradation or improving the stability of PV cells through the formation of a cross-linking network structure during the lamination of the PV module.

What is a framed PV module?

Frame: the majority of PV modules are fitted with an anodized aluminum frame, which hugs the front cover at the top and the back sheet at the bottom. Framed PV modules are better protected than frameless modules during transportation. Fig. 1. Components of a PV module (Reproduced with permission from Ref. . Copyright 2017, Elsevier Ltd). 3.

How does outdoor operation affect the performance of PV cells?

During the long time operation at outdoor conditions, PV cells experience significant morphological and structural changes, optical absorption decay, and impairment of the optoelectronic properties, which adversely affect the performance of the PV module [7, 8].
