Solar Cell Packaging With High Barrier Film

Due to the long-term exposure of solar energy to the air, oxygen and water vapor in the air can easily corrode the metallization layer outside the solar cell, seriously affecting its use. So it is necessary to use high barrier materials for encapsulation of solar cell modules, which not only ensures the service life of solar cells, but also enhances their resistance strength.
The barrier requirements for packaging materials in solar cells are that the water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) should be lower than 10-2g/m2/day and 10-1cm3/m2/day, respectively.
