Problems solved by technology

However, due to the low thermal conductivity of the EVA packaging material (actual measurement is only 0.28W / mk), the thermal resistance of the battery module is mainly at the packaging film; therefore, the actual heat dissipation effect of the above method is not ideal
At the same time, the additional heat dissipation circulation system increases the cost of components, and makes the structure of the whole set of solar energy equipment more complex, and operation and maintenance are more difficult; the corresponding increase in occupied space and weight brings inconvenience to installation and also affects the aesthetics of battery components and practicality

Abstract

The invention relates to a synergistic heat radiation solar cell assembly and a preparation method thereof. The synergistic heat radiation solar cell assembly comprises a frame body good for air flow and an assembly structure mounted in the frame body, wherein the assembly structure consists of a transmission front board, a transparent EVA (Ethylene-Vinyl Acetate copolymer) layer, a solar cell chip and a circuit which are sealed by a packaging glue film, a heat conduction composite EVA back seal glue film and a heat radiation back board in sequence. With the adoption of the synergistic heat radiation solar cell assembly, heat generated by absorbing and coupling when a cell works can be more efficiently transmitted and emitted, so as to effectively reduce the temperature of the cell assembly, improve the light-electric converting efficiency of the cell assembly and be good for delaying the aging damage of the cell damage. According to the invention, the heat transmission effect of the cell assembly is improved through a compound modification method without changing a basic structure and the appearance of the typical solar cell assembly and increasing volume and weight, and is low in cost and convenient for installation, use and maintenance.

Description

【Technical field】 [0001] The invention relates to the technical field of solar cell components, in particular to a solar cell component with synergistic heat dissipation and a preparation method thereof. 【Background technique】 [0002] The ever-increasing demand for energy, as well as the resource and environmental problems faced by traditional fossil energy, make the development and utilization of green renewable energy an inevitable choice for human society. As a clean and renewable energy source, solar energy has been widely used all over the world. Solar photovoltaic power generation can directly produce high-grade energy-electric energy that is convenient for transportation, storage, conversion and utilization, so it is more valued and favored by people. The main problems to be solved in photovoltaic power generation are to further improve the conversion efficiency, prolong the service life and reduce the cost. Solar cell modules are mainly manufactured on the basis o...
