Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a heat dissipation component of a concentrating cell, a packaging method and an application thereof. Background technique [0002] Solar energy is an inexhaustible and inexhaustible clean energy, and using solar power to generate electricity is an environmentally friendly way to use energy. Solar power generation mainly uses solar pools made of crystalline silicon. In order to prevent the surface of solar cells from being oxidized, vacuum packaging or filling rare gas is generally used to encapsulate the surface of the battery. However, the method of vacuum packaging requires relatively high requirements for packaging materials and requires strong pressure , using a rare gas package, the cost is relatively high, because the price of the rare gas is relatively high.

Solar power generation mainly uses solar pools made of crystalline silicon materials. In order to prevent the surface of solar cells from being oxidized, vacuum packaging or filling rare gas is generally used to encapsulate the surface of the battery. , using rare gas packaging, the cost is relatively high, because the price of rare gas is higher

[0003] Using solar cells and metal bonding to conduct heat is an effective solution, but it will short-circuit the solar cells

[0004] When the temperature of the solar cell is higher than 80 degrees Celsius, it needs to dissipate heat. Otherwise, its resistance will increase and the efficiency will be greatly reduced. The current concentrating solar cells use a copper heat dissipation substrate for heat dissipation. The heat dissipation substrate is a solid copper plate, and the heat dissipation effect is not very good. High, limited contact area with air, low heat dissipation efficiency
