Problems solved by technology

The disadvantage of low-temperature color coating is that the hardness of the coating is low, the weather resistance is poor, and the friction resistance is poor. It cannot be used on the outer surface of the glass of photovoltaic modules. surface decoration
[0010] Traditional high-temperature tempered glass coatings are mainly composed of inorganic pigments and glass fluxes, both of which are inorganic components, with outstanding advantages and obvious disadvantages
The advantages are strong hiding power, good weather resistance, good decoration, the same high hardness as tempered glass, the surface coating cannot be scraped off by a knife, and excellent impact resistance. It is suitable for the outer surface decoration of photovoltaic glass and can withstand wind, sand and The impact of objects such as hail; the disadvantage is that the light transmittance of the inorganic coating is very low, and some tempered coatings are not transparent at all, and the light transmittance is only a few percent at the highest. When used for the decoration of colored solar glass panels, the photoelectricity of photovoltaic modules Conversion efficiency is almost zero, no practical application value

Abstract

The invention discloses a solar glass panel with a honeycomb-shaped colored tempered coating, a production method of the solar glass panel and a colored solar photovoltaic module. The production method comprises the following steps: coating a photovoltaic glass panel with a UV colored tempered coating, and preheating the photovoltaic glass panel; after preheating, adopting ultraviolet light for irradiating the UV colored tempered coating; obliquely punching or scribing the preliminarily-cured UV colored tempered coating by adopting a laser beam so as to enable the UV colored tempered coating to form a honeycomb structure; performing high-temperature tempering on the perforated UV colored tempered coating to form the solar glass panel with the honeycomb-shaped colored tempered coating. The UV colored tempered coating comprises the following raw materials in percentage by mass: 8-25% of a thermoplastic polymer, 10-25% of a low-viscosity photoactive diluent, 1-3% of a photosensitizer, 50-65% of a transparent glass flux, 0.1-15% of an inorganic pigment and 0.01-3% of a leveling agent. The coating of the solar glass panel provided by the invention is excellent in shock resistance and has relatively high light transmittance.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a solar glass panel with a honeycomb colored tempered coating, a production method thereof, and a colored solar photovoltaic module. Background technique [0002] Vigorously developing solar photovoltaic power generation is one of the important paths to reduce carbon emissions and achieve carbon neutrality. [0003] Silicon solar photovoltaic cells occupy the mainstream of the market. The traditional structure of silicon solar photovoltaic cells is composed of photovoltaic glass, photovoltaic adhesive film, monocrystalline silicon or polycrystalline silicon solar cells, photovoltaic adhesive film and photovoltaic backplane from the outside to the inside, and is fixed with an aluminum alloy frame. [0004] Since monocrystalline silicon or polycrystalline silicon solar cells are dark blue or black, silicon solar photovoltaic cells are also dark in color. [0005] Distributed so...
