How EVA solar film improves photovoltaic efficiency

EVA solar film is a packaging material widely used in photovoltaic modules. It plays an important role in improving photovoltaic efficiency. The main function of the EVA film is to bond the battery sheets, glass and backsheet together to form a sealed component structure. This material has excellent optical transparency, which ensures that sunlight can penetrate to the maximum extent and be absorbed by the cells, thereby improving energy conversion efficiency. In addition, EVA film also has good aging resistance and UV resistance, can remain stable under various climate conditions, reduce material aging and performance degradation, and extend the service life of photovoltaic modules.

The EVA film also has low water vapor transmission rate and oxygen transmission rate, which means that it can effectively prevent moisture and oxygen from entering the interior of the module, protect the cells from corrosion and oxidation, maintain a dry environment inside the module, and reduce power loss. In addition, the EVA film also has a certain degree of elasticity, which can absorb and disperse the impact of components during transportation and installation to a certain extent, protecting the battery cells from damage.

In general, EVA solar film improves the overall performance and efficiency of photovoltaic modules through its optical transparency, aging resistance, waterproof breathability and elasticity, and is one of the indispensable materials in the photovoltaic industry.
