can eva solar photovoltaic film be degraded?

eva solar photovoltaic films can be partially degraded. eva is a thermoplastic material that decomposes and releases some organic gases at high temperatures. in the natural environment, eva will gradually age and degrade, but this process takes a long time, usually decades or more. in addition, the degradation rate of eva solar photovoltaic film will also be affected by many factors, such as oxygen, ultraviolet rays, temperature, humidity, etc.

eva solar photovoltaic film is used to bond and fix tempered glass and the main body of the power generation. the quality of the transparent eva film directly affects the life of the module. the eva film exposed to the air is prone to aging and yellowing, thus affecting the light transmittance and in addition to the quality of eva itself, the quality of power generation is also greatly affected by the lamination process of component manufacturers. for example, if the cross-linking degree of eva is not up to standard, and the bonding strength between eva and tempered glass and backplane is insufficient, it will cause premature aging of eva and affect the service life of components. .
