Problems solved by technology

[0007] The existing patented technology of color solar energy has low light transmittance, which seriously affects power generation efficiency; or the light transmittance difference between different color coatings is large, which is prone to hot spot effect and burns solar modules; or the coating cannot cover the battery Black background, poor aesthetics, so it is necessary to develop photovoltaic products with richer colors and higher light transmittance

Abstract

The invention discloses a solar panel with a honeycomb color coating, a production method of the solar panel and a color solar photovoltaic module, and the production method comprises the following steps: coating a transparent substrate with a UV color coating, and preheating the transparent substrate; after preheating, adopting ultraviolet light to irradiate the UV colored coating, and enabling the UV colored coating to be subjected to preliminary curing; obliquely punching or scribing the preliminarily cured UV colored coating by adopting a laser beam to form light holes or grooves, so that the UV colored coating forms a honeycomb structure; and performing post-curing on the perforated UV colored coating to form a solar panel with a honeycomb colored coating. The UV colored paint comprises the following raw materials in percentage by mass: 50-70% of a photosensitive polymer; 10-25% of a low-viscosity photoactive diluent; 1-5% of a photosensitizer; 1-15% of a pigment; 0.5-2% of an ultraviolet light absorber; and 0.01-3% of a leveling agent. The UV colored coating has a honeycomb structure, so that the light transmittance of the solar panel is obviously improved.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a solar panel with a honeycomb colored coating, a production method thereof, and a colored solar photovoltaic module. Background technique [0002] my country's construction carbon emissions account for more than 1 / 3 of the total carbon emissions, and the annual new construction area is about 2 billion square meters. Building Integrated Photovoltaics (BIPV) is becoming a solution to create green buildings. [0003] BIPV is a technology that integrates solar power generation products into buildings. The literal understanding is to let the building generate electricity by itself, and directly combine photovoltaic cells and building materials into components, such as wall bricks, tiles, and curtain walls. As one of the best routes for the development of photovoltaic scenario-based applications in the future, BIPV has important demonstration and promotion significance for the real...
