Embodiment 1

[0057] see Figure 5-Figure 8 Shown, as a kind of manufacturing equipment of flexible thin-film solar cell of an embodiment of the present invention, comprise:

[0058] The upper roller 302 is provided with several alternately arranged upper roller cutters 304 and upper roller cutter grooves 305 . Wherein, the alternate arrangement means that one of the upper roller cutters 304 and one of the upper roller cutter grooves 305 are spaced and arranged equidistantly, that is, except for the upper roller cutters located at both ends of the upper roller 302 304 and the upper roller cutter groove 305, each of the upper roller cutters 304 on the remaining positions is arranged on the position directly adjacent to the upper roller cutter groove 305; each of the upper roller The upper roller cutter 304 is arranged directly adjacent to the shaft cutter groove 305; and the upper roller cutter 304 and the upper roller cutter directly adjacent to the upper roller 302 The distance between t...

Embodiment 2

[0066] The manufacturing equipment of a kind of flexible thin-film solar cell described on the basis of the above-mentioned embodiment 1 also includes:

[0067] The platform is used to accept the type I strip thin film solar cell 501 and the type II strip thin film solar cell 502 cut by the cutter, and can drive the type I strip thin film solar cell 501 or the type II strip solar cell 501 as required. The strip-shaped thin-film solar cells 502 are rotated 180 degrees so that adjacent edge tips of adjacent strip-shaped thin-film solar cells face different directions.

[0068] Specifically: first take away all the type I strip thin film solar cells 501 or the type II strip thin film solar cells 502 on the platform, and then turn the platform horizontally by 180 degrees to drive all the strip thin film solar cells 502 on the platform The type II strip thin film solar cell 502 or the type I strip thin film solar cell 501 rotates 180 degrees horizontally. Finally, the orientations...

Embodiment 3

[0071] The manufacturing equipment of a kind of flexible thin-film solar cell described on the basis of the above-mentioned embodiment 1 also includes:

[0072] The manipulator is used to take the type I strip thin film solar cell 501 or the type II strip thin film solar cell 502 on the platform; the manipulator can drive the type I strip thin film solar cell 501 or the type II strip solar cell 502 as required The type II strip-shaped thin-film solar cell 502 is rotated by 180 degrees so that adjacent edge tips of adjacent strip-shaped thin-film solar cells face different directions.

[0073] The production equipment of a flexible thin film solar cell according to the present invention also includes a manipulator for automatically taking strip-shaped thin film solar cells. The type I strip thin film solar cell 501 or the type II strip thin film solar cell 502 meet different rotation requirements.

Abstract

The invention relates to an apparatus and method for making flexible thin-film solar cells. A plurality of alternately arranged cutters and cutter grooves are disposed cooperatively on upper and lower rollers. After cutting, I-type and II-type strip thin-film solar cells arranged alternately are obtained. The strip thin-film solar cells have two edge tips in different directions, and the edge tips of the adjacent strip thin-film solar cells are in the same direction. In the use, the adjacent I-type or II-type strip thin-film solar cells are subjected to plane rotation of 180 degrees and then connected with the II-type or I-type strip thin-film solar cells, so that the adjacent edge tips of the I-type and II-type strip thin-film solar cells connected after rotation are in different directions; and therefore, the flexible thin-film solar cells can be prevented from cutting conductive material in the use, and the stability of electrical connection of the flexible thin-film solar cells is ensured.

Description

technical field [0001] The invention relates to a solar cell manufacturing equipment and method, in particular to a flexible thin-film solar cell manufacturing equipment and method. Background technique [0002] Solar energy is an inexhaustible source of energy that is widely distributed and available without geographical restrictions. Solar cells provide a photoelectric conversion device that generates electricity with minimal environmental impact, and are environmentally friendly and non-polluting, and have attracted more and more attention. High photoelectric conversion efficiency, low cost, durability, easy installation, light weight, and avoiding other environmental impacts are the main directions of solar module research at present. Thin-film solar cells use less material for the light-absorbing layer, and only need a few microns It can effectively convert sunlight energy into electrical energy, and has broad development prospects. Amorphous / microcrystalline silicon,...
