Problems solved by technology

However, once the surface of the heat dissipation film of the above-mentioned solar cell module is damaged, it is difficult to repair. Due to factors such as water vapor entering from this part, there is a possibility that the filler layer will be hydrolyzed and the life of the solar cell unit will be shortened.
In addition, since the existing solar cell modules cannot be used, it is not helpful to improve the heat dissipation effect of the solar cell modules already used outdoors to prolong their lifespan.

Abstract

The present invention provides a heat dissipation sheet for the back face of a solar battery module, and a solar battery module using the same, the heat dissipation sheet being capable of improving heat dissipation properties of solar battery modules already used and also capable of constantly maintaining a heat dissipation function and the like of solar battery modules by replacement. The heat dissipation film preferably has a fine bumpy shape on the entire surface of another face. The heat dissipation film preferably includes a substrate layer in which the adhesive compound layer is laminated on one face side, and a heat dissipation layer laminated on another face side of the substrate layer. The heat dissipation layer preferably includes fine particles, and a binder for the fine particles.

Description

technical field [0001] The present invention relates to a heat sink for the back of a solar cell module, which is attached to the back of the solar cell module and can improve the heat dissipation of the solar cell module. Background technique [0002] In recent years, due to the rising awareness of environmental problems such as global warming, solar power generation with clean energy has attracted attention, and various forms of solar cells are being developed. The solar cell is generally composed of a plurality of solar cell modules which are connected in series or in parallel by encapsulating a plurality of solar cell modules. [0003] The above-mentioned solar cell module is required to have sufficient durability, weather resistance, and the like for long-term outdoor use. like Figure 5 As shown in the figure, the specific structure of a typical solar cell module 41 is that a light-transmitting substrate 42 made of glass or the like and a filler layer made of thermopl...
