Problems solved by technology

During the working process of the photovoltaic module, part of the energy of the battery sheet will be converted into heat energy inside the module, which will increase the working temperature of the module and thus have a negative impact on the power generation efficiency. At present, there are no specific and effective measures for the backplane heat dissipation of photovoltaic modules in the industry

Abstract

The invention relates to the technical field of solar photovoltaic assemblies, in particular to colorful coating glass capable of enhancing the cooling performance of a solar photovoltaic assembly anda preparation method. The colorful coating glass capable of enhancing the cooling performance of the solar photovoltaic assembly comprises a glass substrate and a colorful coating arranged on the glass substrate, and the colorful coating is mainly prepared from, by mass, 3-40% of a filling agent, 3-40% of an adhesive, 1-10% of hexagonal boron nitride, 0.1-20% of pigments, 0.1-20% of auxiliaries,0.1-1% of a catalyst and 20-70% of solvents. By mixing hexagonal boron nitride into the colorful coating, the heat conducting coefficient of the coating is increased, different colorful pigments are added to develop the appearance color needed by the assembly, and the colorful coating glass capable of enhancing the cooling performance of the solar photovoltaic assembly is prepared.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic modules, in particular to a color-coated glass for enhancing the heat dissipation performance of solar photovoltaic modules and a preparation method thereof. Background technique [0002] Generally speaking, the structure of a solar photovoltaic module consists of a front panel glass, a silicon cell, a sealing film on both sides of the cell, and a back sheet. During the working process of the photovoltaic module, part of the energy of the battery sheet will be converted into heat energy inside the module, which will increase the working temperature of the module and thus have a negative impact on the power generation efficiency. At present, there are no specific and effective measures for the backplane heat dissipation of photovoltaic modules in the industry. In addition, since the application range of solar photovoltaic modules is becoming wider and wider, and people have higher and h...
