Abstract

The invention discloses a weather-resistant and high thermal conductive coating, a radiating solar rear panel and an efficient solar cell panel. The weather-resistant and high thermal conductive coating consists of 10 to 50 parts of weather-resistant resin, 5 to 30 parts of curing agent, 0.1 to 5 parts of organic filler, 30 to 80 parts of inorganic filler, and 30 to 100 parts of solvent. The radiating solar rear panel comprises a base layer, and the weather-resistant and high thermal conductive coating is arranged on at least one surface of the base layer or arranged between the base layers. The efficient solar cell panel comprises a solar front panel and the radiating solar rear panel, a solar cell circuit is arranged between the solar front panel and the radiating solar rear panel, and an encapsulation material is arranged on one side or two sides of the solar cell circuit. The weather-resistant and high thermal conductive coating can be directly coated on a base material and has high binding power and an excellent thermal conductive effect, and the weather resistance of the coating meets the requirement of a solar module for the service life of over 25 years.

Description

technical field [0001] The invention relates to a weather-resistant high-thermal-conductivity coating, and also relates to a heat-dissipating solar backboard made by using the weather-resistant high-thermal-conductivity coating, and a high-efficiency solar cell panel made by using the backboard. Background technique [0002] As a green alternative to conventional methods of electricity production, photovoltaic cell modules are used to generate electricity from sunlight. Photovoltaic cell modules are assembled from various semiconductor component systems and must be protected to mitigate the impact and damage of environmental effects such as moisture, oxygen and ultraviolet rays. Photovoltaic cell modules usually use a structure in which EVA is laminated on both sides of the silicon wafer and attached with a protective layer of glass or plastic film. Since the thermal conductivity of the protective layer of glass, EVA, and plastic film is only 0.1-0.8W / m.k, the heat emitted ...
