Solar cell panel passive cooling structure and method based on infrared emission

Abstract

The invention discloses a solar cell panel passive cooling structure and method based on infrared emission. According to the passive cooling structure and method, polyvinylidene fluoride-hexafluoropropylene, acetone and water are mixed and stirred to form a precursor solution; the precursor solution is placed in a container, polyvinylidene fluoride-hexafluoropropylene and water are separated due to evaporation of acetone, micropores with different diameters are formed in polyvinylidene fluoride-hexafluoropropylene, and a cooling material layer is formed; the cooling material layer is attachedto the surface of a front pole electric layer; a high-transmittance material plate covers the cooling material layer to serve as a protective layer, sealing is performed to prevent particulate matterin the air from blocking the micropores, and the function of protecting a solar cell panel is achieved; and the cooling material layer covered by the protective layer is exposed outdoors, so that heatin the solar cell panel is emitted to the space through the cooling material layer and the protective layer in the form of infrared rays. Through the passive cooling structure and method, a passive cooling function can be achieved, so that the purpose of improving power generation efficiency is achieved, and a passive cooling method is provided for the solar crystalline silicon cell panel.

Description

technical field

[0001] The present invention relates to solar photovoltaic power generation systems, including household solar power supplies, transportation fields, communication / communication fields, petroleum / ocean / meteorological fields, photovoltaic power stations, solar buildings, solar cars, etc., and more specifically relates to a system based on infrared Emitted solar panel passive cooling structures and methods. Background technique

[0002] At present, solar photovoltaic power generation is not very popular, mainly because of the problems of high cost, low conversion efficiency and complex system in the use of solar power generation. There are many factors that affect the efficiency of solar power generation. The temperature coefficient of the most commonly used crystalline silicon solar cells is generally -0.4% to -0.45% / °C. Changes in the external environment temperature and the heat generated by the components during the working process will cause the temperatu...
