High-heat-radiation solar cell backboard

Abstract

The invention relates to a high-heat-radiation solar cell backboard comprising a polyester film. A weather-resistant layer is adhered on one side of the polyester film through an adhesive layer. An infrared reflection layer is adhered on the surface of the weather-resistant layer. A weather-resistant adhesive layer is connected on the other side of the polyester film through the adhesive layer. The material of the weather-resistant layer of the solar cell backboard is a fluorine-containing weather-resistant layer, and the solar cell backboard has low cost, great environmental protection performance and better mechanical properties and adhesive strength than those of the conventional backboard so that the backboard structure is more stable and has further prominent solar cell supporting and protection effect. The solar cell backboard is obviously better than the existing backboard, and the reflection performance of the backboard for infrared light can be enhanced by arrangement of the infrared reflection layer so that heat absorption of the whole component is reduced, working temperature of the cell is reduced and the conversion efficiency of the cell is enhanced.

Description

technical field [0001] The invention relates to the field of solar cell backboards, in particular to a solar cell backboard with high heat dissipation. Background technique [0002] Solar energy, as a green and inexhaustible energy source, is undoubtedly the best choice to replace traditional thermal power generation. Since solar cells need to be exposed to the outdoors for a long time, the cells in photovoltaic modules need to be protected to prevent atmospheric pollution. The impact and overlooking of environmental factors such as water vapor, oxygen, and ultraviolet rays. The solar backsheet is one of the accessories of the whole solar cell. It mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. At present, the performance of the solar backsheet with the existing structure is unstable, and the reflectivity, anti-aging performance, and water resistance performance Poor, the complex structure leads to comple...

Problems solved by technology

The solar backsheet is one of the accessories of the whole solar cell. It mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. At present, the performance of the solar backsheet with the existing structure is unstable, and the reflectivity, anti-aging performance, and water resistance performance Poor, complex structure leads to complex processing and increases production costs

In addition, the internal temperature of the existing solar battery backplane will rise rapidly in a high heat environment, which greatly reduces the working efficiency of the solar battery backplane.
