Encapsulate: PV cells as mounted in PV modules are encapsulated with a polymeric material to protect against weather, corrosive environment, UV radiation, low mechanical stress, and low energy impacts. Most often polymeric encapsulate material is ethylene vinyl acetate (EVA) film.
Solar energy is the most-abundant renewable energy-resource and among the various solar techniques, photovoltaic (PV) technology has emerged as a promising and cost-effective approach .
In a study, Surlyn (a copolymer of ethylene & methacrylic acid) has been reinforced by cellulose microfibers, and the composite material was used as encapsulate for the PV module .
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].
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.
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].
