Abstract

The invention relates to the technical field of photovoltaic modules, in particular to yellow cover plate glass for photovoltaic building integration and a preparation method of the yellow cover plateglass. The yellow cover plate glass for photovoltaic building integration is composed of a glass substrate and a plurality of film interference color layers which are arranged from bottom to top. Thefilm material of the multi-layer film interference color layer is a plurality of materials selected from SiO2, TiO2, ZnO, Si3N4, ZrO2, MgF2, SnO2, Nb2O5, Al2O3, ZrN and AlN, and the total thickness of the multi-layer film interference color layer is 140 to 500 nm. According to the yellow cover plate glass for building integrated photovoltaics, by using the glass, a solar cell module can present ayellow appearance, and the efficiency of a solar cell is not obviously attenuated. The invention also provides a preparation method thereof.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a yellow cover glass for photovoltaic building integration and a preparation method thereof. Background technique [0002] The glass curtain walls of buildings usually have a coating that reflects and absorbs light in the mid-light and near-infrared regions of the spectrum to reduce brightness and heat inside the building. Transparent solar panels can harness this energy to reduce electricity demand within the building instead of wasting it. Building integrated photovoltaics can meet the aesthetic requirements, lighting requirements, safety performance requirements, and convenient installation requirements of buildings. It has the advantages of long life and green environmental protection effects, and can effectively reduce building energy consumption and achieve building energy conservation. [0003] The main research direction of the current building-integrated ph...
