Abstract

The invention discloses a manufacturing process for a textured-surface 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 electrode grid lines on the single chip are arranged in an engraving groove; the electrode grid lines comprise a main grid line and multiple thin grid lines that are arranged perpendicular to the main grid line; the number of the main grid line is one, and the main grid line is provided with branch lines; the two ends of the branch lines are communicated with the main grid line; the number of the branch lines is two, and the two branch lines take the main grid line as the symmetrical axis; and the branch lines are arc-shaped lines. By adoption of the process provided by the invention, the sunlight transmittance can be improved; and meanwhile, the charge load capability of a motor can be improved.

Description

technical field [0001] The invention relates to a process for manufacturing a suede solar module. 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, the electrodes are set on the surface of the single sheet, and the charge Insufficient enrichment capacity. There is an urgent need in the prior art for a fabric solar module manufacturing process capable of improving sunlight transmittance. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a fabric solar module manufacturing process capable of improving the sunlight transmittance. [0004] In order to achieve the above object, the technical solution of the present invention is to provide a kind of suede ...
