Abstract

The invention discloses a power-enhanced transparent mesh backplane, which is composed of a mesh layer and a transparent backplane layer, wherein the mesh layer is coated on the transparent backplanelayer. The transparent backplane layer maintains good light transmittance, and the grid layer has good reflectivity, so that the solar ray can be reflected back to the surface of the battery sheet, thereby fully utilizing the solar ray, and comprehensively enhancing the power generation effect of the double glass module. In addition, the backboard designed by the invention has excellent adhesion,insulation, ultraviolet resistance and damp-heat aging resistance, and can ensure the long-term reliability of the double-glass module in the outdoor environment.

Description

technical field [0001] The invention belongs to the field of solar energy packaging materials, and in particular relates to a transparent solar backboard. Background technique [0002] Photovoltaic power generation is a green and clean energy, which is in line with the development direction of energy transformation and plays an important role in the energy revolution. The double-sided double-glass module in the aspect of high-efficiency battery components is a very promising technology in the photovoltaic industry. The cells used in it have the characteristics of generating electricity on the front and back sides, and transparent glass with high light transmittance is generally used in component packaging. Backplane or transparent glass, so as to maximize the power generation of double-glass modules. For the module, the light will pass through the transparent glass and the adhesive film to reach the backplane area. If a white backplane is used or the rear adhesive film is a...
