Inshine E703
Product Features
A UV-light-converting EVA encapsulant film, designed for PV modules requiring UV conversion, such as HJT cells. It has excellent UV-cutoff function within the 290-380nm range to ensure components durability, while converting harmful UV light into usable wavelengths to improve the photoelectric efficiency of the component.
