AI Technical Summary

Problems solved by technology

Due to the high temperature of the traditional welding process, the metal electrode and the crystalline silicon substrate will generate thermal stress due to different expansion / contraction coefficients, which will cause micro cracks (Micro Crack) on the surface of the crystalline silicon.

Embodiment Construction

[0155] Embodiments of the present invention will be described below by way of example with reference to the accompanying drawings. The components shown in the drawings do not represent the actual size of the components, and their thickness, width, or length, etc. are drawn exaggeratedly for the sake of illustration. Meanwhile, in all the drawings, the same component symbols represent the same components.

[0156] In this specification, "electrode tape" refers to a tape having electrodes on its structure. "Electrode" refers to an electrically conducting structure. "Adhesive tape" means a film (Film), strip (Strip), sheet (sheet) and other similar materials including adhesive materials, which are usually continuously rolled into a bundle (roll) for storage, but can also be cut into suitable pieces if necessary. After the length is stacked and stored, or stored in other appropriate ways. At normal temperature, the surface of this film can be sticky or non-sticky. A film on a ...

Abstract

A machine (600, 700, 800) for manufacturing an electrode tape (100, 200, 300, 660, 760, 860) is disclosed. The machine (100, 200, 300, 660, 760, 860) includes a conveyor (610, 710), a conductive structure coil (620, 720, 820), an adhesive material supply unit (630, 730) and a curing unit. The conveyor (610, 710) includes a molding belt (611, 711) with at least one groove (611a, 611b) and a roller (612, 613, 712, 713) used to drive the molding belt (611, 711). The conductive structure coil (620, 720, 820) is adapted to provide a conductive structure (102, 202) to the at least one groove (611a, 611b) of the molding belt (611, 711). The adhesive material supply unit (630, 730) is adapted to provide an adhesive material (101, 201, 301, 661) to a surface of the molding belt (611, 711). The curing unit is adapted to cure the adhesive material (101, 201, 301, 661) provided on the surface of the molding belt (611, 711) into a film.

Description

technical field [0001] The present invention relates to a production machine of electrode tape, in particular to a production machine of double-sided adhesive and double-sided conductive electrode tape. Background technique [0002] Solar cells use the photoelectric conversion effect to convert sunlight into electrical energy, which is a clean energy source without pollution. At present, solar cells have been extensively researched and produced, and gradually began to replace traditional electricity. [0003] Common solar cells are semiconductor components including n-p junctions, such as monocrystalline silicon, polycrystalline silicon, amorphous silicon or other thin film semiconductor components with n-p junctions. The n-p junction is usually fabricated by doping n-type or p-type ions into the interior of the semiconductor device by means of diffusion or ion implantation. When light is irradiated to a semiconductor component, electrons and holes of semiconductor element...
