In a study, a UV curable acrylate adhesive with phenyl ether functionality has been employed as encapsulate for the PV module . Phenyl ether groups enhanced the barrier performance of acrylate encapsulate by providing hydrophobicity to the acrylate matrix and also promoted their adhesive nature with untreated PET substrate.
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].
In a study, to prolong the lifetime of the PV cell, EVA is reinforced with the acid-functionalized graphene nanoplatelets (GNP), and the effect of concentration of GNP on the thermo-mechanical, barrier, and optical properties of the EVA composite film has been investigated .
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.
Encapsulation is an effective and widely accepted tool for enhancing the operation stability of the PV cells, by preventing the weather-related (moisture, UV light, oxygen, and temperature) degradation and strengthening the mechanical toughness against external impacts .
Two PV cells were laminated with neat EVA and doped EVA sheets and were allowed for thermal conductivity studies. The thermal conductivity of the doped EVA increased from 0.23 W/m.K to 0.83 W/m.K with an increase in BN concentration. The doped laminate was ∼6% cooler than standard laminate during the unidirectional heat flux exposure.

The ETFE film is typically bonded to the solar cell with an EVA encapsulant to form a front surface protective laminate. Strong ETFE-EVA adhesion is a critical requirement to ensure long-term durability of PV modules. However, ETFE''s low surface energy and inertness is a challenge to achieve sufficient EVA adhesion.
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
