Problems solved by technology

The back film is mostly a polymer composite material containing fluorine (the thermal conductivity is only 0.1-0.2W / m.K), which plays a protective role in water blocking and insulation, but at the same time it brings the problem of difficult heat dissipation

Abstract

The invention discloses a high-heat-dissipation solar cell assembly which is characterized by comprising a front plate material layer (1), an upper packaging material layer (2), a cell (3), a lower packaging material layer (4) and a rear plate glass layer (5) which are stacked sequentially from top to bottom, wherein the lower packaging material layer (4) is doped with 10%-30% of thermal conductive particles by weight, and the rear plate glass layer (5) is doped with 1%-10% of thermal conductive particles by weight. By means of the high-heat-dissipation solar cell assembly, the number of heat generation sources can be reduced, heat generated when the assembly works can be dissipated out as much as possible, and therefore, shortcomings in the prior art can be overcome. The high-heat-dissipation solar cell assembly is easy to implement due to the fact that there's no need to change the packaging process of an existing product.

Description

technical field [0001] The invention belongs to the field of photovoltaic technology, and in particular relates to a high heat dissipation type solar cell assembly Background technique [0002] With the development of human civilization, the world is facing serious energy crisis and environmental pollution. Among them, photovoltaic solar cells, which can directly convert solar energy into electrical energy, are one of the important methods to solve the world's energy crisis and reduce environmental pollution. Modules composed of solar cells are usually exposed to the sun. In order to avoid solar radiation from affecting the temperature of the battery module and thus affecting the power generation efficiency of the battery module, it is particularly required that the solar power module has good heat dissipation performance. [0003] Research data show that the same photovoltaic module power station, in spring and autumn with weak light intensity and short light time, and sum...
