There are other materials also continuously being tested for their ability to serve as a good encapsulant.Įncapsulation provides structural and positioning support to the solar cell in the module design layout throughout manufacturing, transport, storage, installation, and use. However, EVA is not the only material used to encapsulate solar cells. Since EVA is inexpensive and has good optical properties, it serves as a good encapsulant for solar cells. In fact, EVA encases over 80% of photovoltaic (PV) modules on the market today. The most common encapsulating material used for this purpose is EVA (Ethylene-vinyl acetate). The goal of encapsulation is to provide the mechanical support and environmental isolation required by the cells and electrical wire system to ensure their electrical performance. This brings the need to protect solar cells through packaging and encapsulation. Also, environmental factors like rain, dust, and external electric fields can create a negative effect on the performance of solar cells. Solar cells are susceptible to brittleness failure under physical stress like bending and tension. Solar PV modules are made up of strings of solar cells that are linked together and capable of generating useful amounts of electricity when exposed to sunlight.
