introduction to eva solar photovoltaic film packaging structure

introduction to eva solar photovoltaic film packaging structure. photovoltaic adhesive film is a material that plays a key role in the packaging of photovoltaic modules and is one of the materials of photovoltaic modules. the adhesive film bonds photovoltaic cells, photovoltaic glass and backsheets. its main function is to protect the cells and package them into photovoltaic modules that can output dc power. if the film has problems such as a decrease in light transmittance during use, the module is likely to be unable to generate electricity normally and be scrapped. therefore, photovoltaic modules have relatively high requirements for the adhesive film used in packaging, especially in terms of light transmittance, weather resistance, bonding strength, aging resistance and other properties.
