Polyester films for solar cells are used to make backsheets that protect the back side of solar modules. There are two types of film, SG00L and SW30G. The weather-proof PET film, SG00L with triple structure, can be used to substitute fluorine film as the outer material for the backsheet. It acts as both the external and internal material. SW30G protects the backsheet from ultraviolet rays and maximizes the conversion efficiency of modules by raising reflectance.
Major products | Features |
---|---|
SW00L | White film is used in the outermost part of the backsheet as it has good weather resistance |
DW00L | A film with white appearance and triple structure, capable of playing the role of a core layer and an outermost layer |
SG00L | Transparent film used for the core layer of the backsheet as it has low heat shrinkage and good weather resistance |
SW30G | White film that strengthens reflectance of the backsheet with inner ultraviolet film, resulting in high efficiency |
