Embodiment 1

[0031] Such as figure 2 Shown, a kind of preparation method of solar cell assembly comprises the following steps:

[0032] Step S101, performing scribing processing on the solar cell, and dividing the solar cell into n regions, wherein the scribe line is set between two adjacent busbar lines in the solar cell, and n is greater than 1 and less than or equal to The number of busbars in a solar cell.

[0033] In the embodiment of the present invention, such as image 3 and Figure 4 As shown, the solar cell 300 is provided with main grid lines 301 and thin grid lines (not shown in the drawings), and the main grid lines 301 are perpendicular to the thin grid lines. Through the laser scribing process, n-1 scribed lines 302 are scribed in the solar cell 300, the direction of the scribed lines 302 is the same as the direction of the bus bar 301, and the length of the scribed lines 302 is the same as that of the solar cell 300. have the same length, the solar cell is divided into...

Abstract

The invention is applicable to the technical field of photovoltaic power generation and provides a preparation method of a solar cell module and thesolar cell module, The method comprises the following steps: the solar cell sheet is scratched and carved, and the solar cell sheet is divided into n regions, wherein, the scratched and carved lines are arranged between two adjacent main grid lines inthe solar cell sheet, n is greater than 1 and less than or equal to the number of main grid lines in the solar cell sheet; A plurality of scribed solar cell sheets are serially connected into a battery string through a welding strip; A plurality of battery strings are connected in parallel by bus strips, wherein, the plurality of battery strings are connected with welding strips led out at the upper ends of two adjacent battery strings through one bus strip, and the plurality of battery strings are connected with welding strips led out at the lower ends of two adjacent battery strings throughm bus strips, and m is less than or equal to n. The invention can reduce the loss of the welding ribbon and improve the output power of the solar cell module.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a method for preparing a solar cell assembly and the solar cell assembly. Background technique [0002] A solar cell is a device that converts solar energy into electrical energy, and is an ideal clean energy source. When using a solar cell, it is necessary to package the solar cell into a solar cell module. Such as figure 1 As shown, in a traditional solar cell module, a plurality of solar cells 100 are connected in series to form a battery string through a soldering ribbon 101 , and then the battery strings are connected side by side by using a busbar 102 . However, due to the electrical loss caused by the solder ribbon, the output power of the solar cell module is reduced. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a method for preparing a solar cell assembly and the solar cell asse...
