Method for Electrically Connecting Solar Cells

Abstract

A method for connecting solar cell plates electrically includes the following steps: providing a plurality of solar cell plates, wherein each solar cell plate is provided with a first surface and a second surface opposite to the first surface; arranging the solar cell plates in parallel to enable the first surfaces and the second surfaces opposite to the first surfaces of the solar cells to be located in two planes parallel to each other; fixing the solar cell plates placed in the parallel arrangement with a fixing structure; connecting the solar cell plates electrically with a first conductive structure coated with first conductive glue, wherein an external force is exerted on the first conductive glue to enable the first conductive glue to move in the direction far away from the surfaces of the solar cell plates until the first conductive glue is solidified. The method for connecting the solar cell plates electrically can prevent a PN junction short circuit and is suitable for a large-batch production process.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a method for electrically connecting solar cells. Background technique [0002] In recent years, due to serious problems such as energy shortage and environmental pollution, solar energy has become one of the most important solutions to these problems. With the rapid development of solar cells and semiconductor industries, solar cells have been widely used in various fields. [0003] In the practical application of solar cells, in order to obtain a larger input current, it is usually necessary to connect multiple solar cells in parallel to form a solar cell module. In order to improve the efficiency of the module and reduce the cost of the module, it is necessary to reduce the thickness of the solar cells and the gap between them. However, the reduction of the thickness and the gap, due to the capillary phenomenon, the conductive glue used to bond the wire and the solar cell will ente...

AI Technical Summary

Problems solved by technology

However, the reduction of the thickness and the gap, due to the capillary phenomenon, the conductive glue used to bond the wire and the solar cell will enter the gap between the solar cells, resulting in a short circuit of the PN junction, which will cause the solar cell module to fail. normal work

Therefore, although thin solar cells can greatly save battery materials and reduce the cost of solar cells, the existing technology is not suitable for mass production of solar cell modules with small gaps and parallel connections with thin solar cells.
