Embodiment 1

[0023] Embodiment 1: As shown in Fig. 1 and Fig. 2, the inner concentrating solar photoelectric photothermal composite tube. By bonding the polycrystalline silicon solar cell 2 on the metal heat collecting strip 1, the copper welded on the metal strip 1 The heat pipe 3, the trough-shaped reflective concentrator 4 and the encapsulated transparent glass tube 5 are composed. The trough-shaped reflective concentrator 4 gathers the incident sunlight to the polycrystalline silicon solar cells 2 on the front and back of the metal heat-collecting strip 1.

[0024] The metal strip 1 shown in Figure 3 is an aluminum strip with good thermal conductivity, which is used as a heat sink for solar cells and should be bonded with the polysilicon battery sheet 2 through an insulating heat-conducting adhesive 6. The other side of the aluminum strip 1 Deposition of solar selective heat collecting coating 1.1.

[0025] As shown in Figure 1 and Figure 2, the evaporation section 3.1 of the copper he...

Embodiment 2

[0032] Embodiment 2: as Fig. 4, Fig. 5, shown in Fig. 6, present embodiment and embodiment 1 are basically the same. Only following two points are different:

[0033] 1. The copper heat pipe 3 in Fig. 1 of embodiment 1 is changed to the copper pipe 3 in Fig. 5 and Fig. 4 of this embodiment, and is closed at one end 3.1. The heat generated by the inner concentrating solar photoelectric photothermal composite pipe can pass through the copper pipe The working medium of the inner circulation is delivered to the user.

[0034] 2. As shown in Figure 5 and Figure 6, the side of the polycrystalline silicon solar cell 2 faces upwards and directly absorbs the incident sunlight. The solar selective heat-collecting coating 1.1 deposited on the aluminum strip 1 faces downwards and absorbs the trough-shaped reflection and concentration Sunlight reflected by device 4.

[0035] The foregoing embodiments are only two implementations of the present invention, and are only used to illustrate th...

Abstract

The invention is concerned with photovoltaic and photo-thermal multiple tube of concentrated solar energy. It relates to crystal silicon solar cell felted on the metal heat collector bar, metal pipe felted on this metal bar, echo concentrator in groove shape and encapsulation transparent glass pipe. The echo concentrator in groove shape collects the incident sun's rays to metal heat collector bar and the crystal silicon solar cell on the other face. The glass pipe is vacuum or filled with nitrogen and the solar energy cell is closed in it to avoid oxidation, damp and erosion. A part of the absorbed solar energy changes into electricity and educes outside of glass pipe by metal lead. And a part changes into heat and carries to metal pipe by metal bar, and continues carries out of glass pipe by the matter inside it. It reduces the cell's work temperature and increases photoelectric conversion efficiency. The pipe has higher work temperature of solar cell by generate electricity and heat together.

Description

[0001] Field [0002] The invention relates to the combination of solar photoelectricity, light and heat, specifically an inner concentrating solar photoelectricity, light and heat composite tube. Background technique [0003] At present, solar photovoltaic power generation widely uses crystalline silicon cells or thin-film cells such as amorphous silicon and copper indium selenium to be packaged into plate-shaped modules. The heat energy absorbed by solar panels is not used, which causes the operating temperature of solar panels to rise and reduces the photoelectric conversion. efficiency. [0004] The cost of non-concentrating flat-panel solar cells is high. [0005] At present, all kinds of solar panel or vacuum tube collectors only have the function of light-to-heat conversion, and can only supply heat, such as domestic hot water. They cannot generate electricity. [0006] Therefore, it is necessary to invent an inner concentrating solar photoelectric photothermal compos...
