● Introduction
Ultra-clear PV glass is ultra clear rolled glass and is also called ultra-clear wove (patterned) glass. It is mainly used as sealing glass of solar cells and is an indispensable part of photovoltaic solar cells. It enjoys outstanding performance such as high sun light transmittance, low absorption rate, low reflectivity, and low iron content and is the most ideal packaging material for solar photovoltaic and photo-thermal transformation systems. It can largely improve photo electric and photothermal conversion efficiency.
● Application
The non-toxic composition of Xinyi’s ultra-clear PV glass fully conforms to the strict requirements of Europe, U.S. and Japan for environment protection. It is ideal packaging material for solar photovoltaic and solar thermal components.
