Problems solved by technology
[0002] As we all know, in the existing photovoltaic modules, the electrodes are printed on both sides of the single sheet in the silk screen printing process. Such electrode settings will block part of the sunlight no matter how thin the electrode grid is; at the same time, there is no anti-reflection component on the surface of the single sheet Not conducive to improving the transmittance of sunlight

Abstract
The invention discloses a production method for a spiral electrode solar module. The process comprises the steps of cleaning, doping, printing, sintering, performing single-chip test, performing welding of a positive electrode and a negative electrode of a photovoltaic cell piece, laminating, performing detection on a photovoltaic cell pack piece, laminating and curing, and performing frame formation, wherein the single chip is provided with the positive electrode and the negative electrode; the positive electrode and the negative electrode winds from the centre of the single chip to the outside to form an Achimedean spiral; the positive electrode and the negative electrode are arranged on the same surface of the single chip at intervals; an isolating band is arranged between the positive electrode and the negative electrode; the positive electrode and the negative electrode are 0.05-0.1mm in thicknesses; and a silicon nitride antireflection film is arranged on the surface of the single chip. By adoption of the process provided by the invention, the sunlight transmittance can be improved.
Description
technical field [0001] The invention relates to a production method of a spiral electrode solar component. Background technique [0002] As we all know, in the existing photovoltaic modules, the electrodes are printed on both sides of the single sheet in the silk screen printing process. Such electrode settings will block part of the sunlight no matter how thin the electrode grid is; at the same time, there is no anti-reflection component on the surface of the single sheet It is not conducive to improving the transmittance of sunlight. There is an urgent need in the prior art for a production method of a spiral electrode solar module that can improve the transmittance of sunlight. Contents of the invention [0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a method for producing a spiral electrode solar module capable of improving the sunlight transmittance. [0004] In order to achieve the above object, the tec...
