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.
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.
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].
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.
To fabricate a lightweight solar cell module, we used a 0.025 mm-thick PET film sheet as both a front-cover and a backsheet. The solar cells were encapsulated with EVA. As a reference sample, we fabricated solar cell modules with 3.2 mm-thick glass as the front-cover material. The sample structures are shown in Fig. 1.
The fabricated modules have flexible properties. The lightweigh and flexible modules exhibit high reliability under both high temperature and high humidity conditions. Lightweight and flexible solar cell modules have great potential to be installed in locations with loading limitations and to expand the photovoltaics market.

Solar panel
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
