Embodiment 1

[0020] Small-area independently packaged monocrystalline silicon solar cells (3) are arranged in an array, and ethylene-vinyl acetate copolymer (EVA) is bonded on the polyester cloth base (2), and the adjacent independently packaged solar cells should be The gap is left to make the assembled solar cell device flexible. The solar cell is covered with a polytetrafluoroethylene composite film (1) with high light transmittance, and the positive and negative electrodes of the solar cell are connected in series or in parallel through wires to form a flexible solar cell device as a whole.

Embodiment 2

[0022] Arrange the small-area independently packaged polycrystalline silicon solar cells (3) into an array, and bond them to the polymer film (2) with polyvinyl butyral, leaving gaps between adjacent independently packaged solar cells to allow assembly A good solar cell device is flexible. The solar cell is covered with a high-transmittance polyester film (1), and the positive and negative terminals of the solar cell are connected in series or in parallel through wires to form a flexible solar cell device as a whole.

Embodiment 3

[0024] Arrange small-area independently packaged amorphous silicon solar cells (3) into an array, and bond them to the polymer-based composite film (2) with silicone resin. There should be gaps between adjacent independently packaged solar cells, so that The assembled solar cell device is flexible. The solar cell is covered with a high-transmittance polytrifluoroethylene composite film (1), and the positive and negative electrodes of the solar cell are connected in series or in parallel through wires to form a flexible solar cell device as a whole.

Abstract

The present invention relates to a curling and foldable soft solar battery device. The present invention is characterized in that the present invention arrays the independent solar battery(3) and sticks on the curling and foldable soft soleplate(2) by the adhesive; the solar battery is covered with a high light transmit efficiency soft film(1); the present invention educes the positive and negative guiding feet parallel or in series through leads to form the soft solar battery device. The present invention has the advantages of light weight and the present invention is movable, curling and foldable; the present invention brings convenience to the transport and the pave; and the present invention is applicable to the fire balloon, the car ceil, the plane wing, the touring boat, the decorative light, the advertising light and the tent.

Description

technical field [0001] The invention relates to a rollable and foldable flexible solar battery device, which belongs to the application field of solar batteries. Background technique [0002] At present, the general silicon solar cell module integrates low-iron tempered glass, cell array, adhesive and transparent film, and assembles a frame around it to protect the glass. This device is suitable for large-scale construction fields such as solar power stations and roofs. , such as US Pat. No. 4,167,644 and US Pat. No. 4,104,083 respectively disclose solar cell modules with rigid base plates. Although there have been a series of improvements in the future, the basic feature of silicon solar cell modules is still to install cell arrays on rigid substrates. The above-mentioned traditional solar cell module not only has a rigid base plate, but also has a large weight, which limits its application range, and is not suitable for many occasions, such as hot air balloons, tents and ...
