LIGHT-CONCENTRATING PHOTOVOLTAIC GLASS WITH LINEAR FRESNEL LENS PATTERNS

摘要

A light-concentrating photovoltaic glass (1) with linear Fresnel lens patterns is provided, one surface of the glass is flat, and the other surface of the glass is composed of multiple groups of light-concentrating units. The glass has high light transmittance and good light-concentrating effect by using the light-concentrating units structure designed on a surface of the photovoltaic glass, the glass can be used for a solar photovoltaic module and light-thermal application. The light-concentrating photovoltaic glass(1) has light-concentrating function when being used for the solar photovoltaic module, width L of a silicon chip(2) placed under the glass is not greater than that of one light-concentrating unit, light received on the silicon chip per unit area is increased, and dosage of the silicon chip is reduced.
