Abstract

The invention relates to the technical field of photovoltaic modules, in particular to blue cover plate glass for photovoltaic building integration and a preparation method of the blue cover plate glass. The blue cover plate glass for photovoltaic building integration is composed of a glass substrate, a color layer and a protective layer which are arranged from bottom to top. A film layer materialof the color layer is one of or a mixture of more of SiO2, TiO2, ZnO, Si3N4, MgF2, SnO and Nb2O5, and the thickness of the film layer material is 80-200 nm; and the film material of the protective layer is one of or a mixture of more of TiN, ZrO2, ZrN, SiZrOx, SiZrN and SiZrON, and the thickness of the protective layer is 3-15nm. According to the blue cover plate glass for photovoltaic building integration, the reflection color value is sapphire blue, the blue cover plate glass is used for a photovoltaic solar cell, the solar light transmittance (380 nm-1100 nm) is larger than 85%, and the efficiency of the solar cell is basically unchanged; and the invention also provides a preparation method of the blue cover plate glass.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a blue cover glass for photovoltaic building integration and a preparation method thereof. Background technique [0002] BIPV is a new concept of applying solar power generation. Simply put, it is to install solar photovoltaic power generation arrays on the outer surface of the building envelope to provide electricity. Generally, paint, decorative tiles or curtain wall glass are used on the outer surface of the building to protect and decorate the building. If photovoltaic devices are used to replace some building materials, that is, photovoltaic modules are used to make roofs, exterior walls and windows of buildings, which can be used as both building materials and power generation. For buildings with a frame structure, the entire enclosure structure can be made into a photovoltaic array, and appropriate photovoltaic modules can be selected to absorb both direct su...
