Embodiment 1

[0110] This embodiment illustrates the heat dissipation effect of the solar cell panel on the back plate with square-arranged spherical protrusions used in the present invention.

[0111] like Figure 21 As shown, the solar cell in this example consists of three parts: the front plate (tempered glass, purchased from Dongguan CSG Solar Glass Co., Ltd., 3.2 mm thick), the polysilicon solar cell circuit (125×125×0.3 mm, 72 pieces connected in series) and the back plate. composition. The backsheet is a laminated film consisting of two 25-micron thick polyvinyl fluoride films ( PV2001, a layer of thick polytrimethylene terephthalate film ( DuPont Company of the United States), and formed by hot pressing under vacuum conditions. After these three parts are hot-pressed together with two layers of ethylene-vinyl acetate copolymer (Ruifu brand photovoltaic cell EVA film, R767, purchased from Wenzhou Ruiyang Photovoltaic Material Co., Ltd.) with a thickness of 700 microns, The sid...

Embodiment 2

[0116] This embodiment illustrates the heat dissipation effect of the solar cell panel on the back plate with spherical protrusions closely arranged in four directions used in the present invention.

[0117] like Figure 21 As shown, the solar cell in this example consists of three parts: the front plate (tempered glass, purchased from Dongguan CSG Solar Glass Co., Ltd., 3.2 mm thick), the polysilicon solar cell circuit (125×125×0.3 mm, 72 pieces connected in series) and the back plate. composition. The backsheet is a laminated film consisting of two 25-micron thick polyvinyl fluoride films ( PV2001, a layer of thick polytrimethylene terephthalate film ( DuPont Company of the United States), and formed by hot pressing under vacuum conditions. The three parts were hot-pressed together with two layers of ethylene-vinyl acetate copolymer (Ruifu brand photovoltaic cell EVA adhesive film, R767, purchased from Wenzhou Ruiyang Photovoltaic Material Co., Ltd.) with a thickness of ...

Embodiment 3

[0120] This embodiment illustrates the heat dissipation effect of the solar cell panel on the back plate with hexagonal closely arranged spherical protrusions used in the present invention.

[0121] like Figure 21 As shown, the solar cell in this example consists of three parts: the front plate (tempered glass, purchased from Dongguan CSG Solar Glass Co., Ltd., 3.2 mm thick), the polysilicon solar cell circuit (125×125×0.3 mm, 72 pieces connected in series) and the back plate. composition. The backsheet is a laminated film consisting of two 25-micron thick polyvinyl fluoride films ( PV2001, a layer of thick polytrimethylene terephthalate film ( DuPont Company of the United States), and formed by hot pressing under vacuum conditions. The three parts were hot-pressed together with two layers of ethylene-vinyl acetate copolymer (Ruifu brand photovoltaic cell EVA adhesive film, R767, purchased from Wenzhou Ruiyang Photovoltaic Material Co., Ltd.) with a thickness of 700 micr...

Abstract

The invention discloses a solar panel with improved heat radiation performance. The solar panel comprises a front panel, a back panel and a solar battery circuit arranged between the front panel and the back panel. The back panel is provided with a second main surface adjacent to the solar battery circuit, and a first main surface contacted with the ambient condition. The solar panel is characterized in that the first main surface is provided with a plurality of surface bulges.

Description

technical field [0001] The present invention relates to a solar panel with improved heat dissipation. Background technique [0002] With the warming of the global climate, the governments of various countries have higher and higher requirements for energy saving and emission reduction. Therefore, finding new energy sources to replace fossil fuels has become an urgent problem to be solved. [0003] Solar energy is a clean, pollution-free and inexhaustible source of energy. At present, solar energy is mainly converted into electrical energy through solar panels, which is then used to drive electric water heaters, electric vehicles, satellite components, etc. [0004] A solar panel is a photoelectric element that directly generates electricity from light, especially sunlight. Existing solar panels mainly include a backsheet, a solar cell circuit, an encapsulation material and a front sheet. [0005] The role of the encapsulant in the solar panel, such as ethylene-vinyl acet...
