Low iron patterned glass also can be said :Ultra-clear PV 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.
