Glass panel for solar photovoltaic cell and preparation method thereof

Abstract

The invention belongs to the technical field of an assembling type environment-friendly energy-saving building and solar energy comprehensive utilization, and particularly to a glass panel in the thinfilm power generation field of a glass curtain wall or a glass roof for a building external fa ade, and particularly to a glass panel for a solar photovoltaic cell and a preparation method thereof. The glass panel for the solar photovoltaic cell comprises a substrate. The substrate is divided into a pattern area and a contrasting area. A plurality of pattern area optical structure unit configurations are arranged and fixed in the pattern area. A plurality of contrasting area optical structure unit configurations are arranged and fixed in the contrasting area. The glass panel and the preparation method thereof have advantages of (1), no luminous flux is changed, great light transmittance reduction of incident light is prevented, and high power generation efficiency is ensured; (2), throughstructure change of the geometric configuration, color brightness change is generated, thereby improving visual impact of a decorative pattern; and (3), decorative performance of the photovoltaic glass curtain wall and the roof is improved, and furthermore great increase of manufacturing cost is prevented.

Description

technical field [0001] The invention belongs to the technical field of prefabricated green energy-saving buildings and comprehensive utilization of solar energy, and in particular relates to a glass panel in the field of thin-film power generation for glass curtain walls or glass roofs used on building facades, in particular to a glass panel for solar photovoltaic cells and its preparation method. Background technique [0002] According to data, building energy consumption accounts for about 1 / 4 of my country's total energy consumption. Therefore, with the rapid economic development and the acceleration of urbanization, energy demand continues to increase, which intensifies the energy crisis. How to promote building energy conservation has become a hot issue that needs to be solved urgently. At present, prefabricated green and energy-saving buildings have become a bright spot in building energy conservation due to their advantages such as fast construction speed, labor-savi...
