Flexible gallium arsenide component and manufacturing process thereof

Abstract

The invention relates to the technical field of solar cells, in particular to a flexible gallium arsenide component and a manufacturing process thereof. The flexible gallium arsenide component comprises a battery array, a light receiving surface of the battery array is connected with a second fluorine-containing film through aerospace glue; second Teflon high-temperature cloth is arranged on the side, away from the battery array, of the second fluorine-containing film; tempered glass is arranged on one side, far away from the second fluorine-containing film, of the second Teflon high-temperature cloth; the side, away from the second fluorine-containing film, of the battery array is connected with a first fluorine-containing film through space glue; and first Teflon high-temperature cloth is arranged on the side, away from the battery array, of the first fluorine-containing film. Through small-area overlapping and interconnection of the gallium arsenide battery pieces, the distance between the battery pieces in series connection is completely eliminated, the laying area is utilized to the maximum extent, spaceflight glue and a fluorine-containing film are selected as packaging materials in a vacuum environment and under a certain pressure condition, the gallium arsenide component can be bent, and the gallium arsenide component is suitable for being used in different applicationfields.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a flexible gallium arsenide component and a manufacturing process. Background technique [0002] The existing space solar modules are basically gallium arsenide battery modules pasted with glass covers on the front and using silver foil as interconnection bars. In the later stage of module processing, it is necessary to paste the glass cover sheet and the interconnected gallium arsenide cell string on the aluminum plate or aluminum honeycomb board to form a solar module for space with aluminum substrate + gallium arsenide cell and glass cover sheet. Because this type of module uses silver foil interconnection, the gap between the cells is relatively large, and the number of gallium arsenide cells laid per unit area is limited. At the same time, because the upper surface of the cell is pasted with a glass cover, and the base of the lower surface is an aluminum substrate, Ther...

Because this type of module uses silver foil interconnection, the gap between the cells is relatively large, and the number of gallium arsenide cells laid per unit area is limited. At the same time, because the upper surface of the cell is pasted with a glass cover, and the base of the lower surface is an aluminum substrate, Therefore, the surface density of the component is relatively large and cannot be bent
