Serpentine channel solar cell waste-heat recovery unit

Abstract

The invention discloses a serpentine channel solar cell waste-heat recovery unit, belonging to the technical field of solar cell preparation. The serpentine channel solar cell waste-heat recovery unit is mainly composed of a photovoltaic template cell system and a waste-heat recovery unit, wherein the photovoltaic template cell system is composed of a front glass cover plate 1, an air layer 2, a solar cell 3 and a back glass cover plate 4; and the waste-heat recovery unit comprises a serpentine water flow channel 6, a water inlet 7, a water outlet 8, a water inlet connection box 9 and a water outlet connection box 10. A transparent silica gel 5 bonds the serpentine water flow channel 6, the water inlet connection box 9 and the water outlet connection box 10 in one group onto the back glass cover plate 4, the components are sequentially welded together, and an upper insulation layer 11 is installed on the other side of the serpentine flat box water flow channel 6. The unit disclosed by the invention does not need additional occupation room, can lower the battery temperature, can enhance the photoelectric conversion efficiency, and can prolong the service life of the cell, thereby satisfying our demands for hypothermal water in daily life and preventing thermal pollution.

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to a recovery device for waste heat of a serpentine channel solar cell. Background technique [0002] With social progress and economic development, we are increasingly dependent on energy consumption, disposable energy is gradually exhausted, and the development and utilization of renewable energy is becoming more and more urgent. Solar energy resources are extremely common, and are non-polluting and inexhaustible, which meets the current world environmental protection requirements. The use of solar photovoltaics to generate electricity is an example of application all over the world. Solar power generation has been widely promoted by various countries, and the market potential of solar cells is huge. When sunlight hits a solar cell, a photoelectric conversion reaction begins inside the cell. However, only a small part of the sunlight put into the phot...

Problems solved by technology

However, only a small part of the sunlight put into the photovoltaic template is converted into electrical energy and output, and more than 90% of the light energy is converted into heat energy. Part of the converted heat energy raises the temperature of the battery, and part of it is converted into heat energy. The form is emitted into the surrounding air, causing thermal pollution of the surrounding environment

In addition, the power generation efficiency of the photovoltaic power generation template is greatly affected by its own temperature, which is almost inversely proportional to the temperature. If the heat is not dissipated in time, the temperature of the solar cell will rise sharply, and the photoelectric conversion efficiency of the cell will drop sharply. Will shorten the service life of the battery board
