Abstract

The invention provides a production method of a solar battery component and a solar battery component, and relates to the technical field of solar photovoltaics. The method includes: making a battery sheet precursor with a ribbon groove at least part of the edge; the ribbon groove connecting the first surface and the second surface of the battery sheet precursor; the first surface is the battery sheet The light-receiving surface or the backlight surface of the precursor; the second surface is perpendicular to the first surface; busbar lines are arranged on the first surface of the battery sheet precursor to obtain a battery sheet; the busbar lines The end of the battery sheet is aligned with the ribbon groove on the battery sheet precursor; the ribbon is laid on the bus bars and the ribbon grooves of several battery sheets, and based on the ribbon string Welding the battery sheets to obtain a battery string; packaging the battery string to obtain a solar cell module. The present application greatly reduces cracks, reduces the size of gaps that need to be left between battery sheets, and improves power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaics, in particular to a method for producing a solar cell assembly and the solar cell assembly. Background technique [0002] In the solar photovoltaic industry, solar cell modules packaged by cell sheets can increase the power of photovoltaic modules per unit area, thereby reducing the cost of solar cells, so they are widely used. [0003] At present, in the process of packaging cells into solar cell modules, it is necessary to use solder ribbons to connect the positive busbar of the previous cell and the negative busbar of the next cell to achieve current collection and transmission. [0004] The above existing technical solutions have the following disadvantages: due to the height difference between the positive busbar of the previous cell and the negative busbar of the next cell, the welding ribbon needs to be bent into a "Z" shape, which is easy to cause cracks, and the battery A lar...
