PET film is mainly heat-resistant and aging. Generally, the test method of 120 ℃, 100% RH resistance to hydrolysis is adopted. The time for cracking and embrittlement of the PET film shall not be less than 96h. The longitudinal shrinkage of PET film can generally be controlled below 1.5% (150 ℃, 30 min). Since solar photovoltaic cells need to undergo three high-temperature treatments, this requires the substrate of the battery backsheet to have excellent dimensional stability. PET film must have good tear resistance and toughness, and avoid easy tearing and embrittlement during component processing and outdoor wet, hot, dry, and cold environments. As a new energy source, solar photovoltaic system has a wide range of applications. Its application fields are mainly in space vehicles, communication systems, microwave relay stations, TV differential turntables, photovoltaic water pumps, industrial and agricultural power generation, regional power supply, traffic signs, civil lighting, etc. .
