Solar cell component and manufacturing method thereof

Abstract

The invention provides a solar cell component, which comprises a solar cell, a first conductive piece and an insulating layer, wherein first electrodes which are mutually insulated and isolated and second electrodes opposite to the first electrodes in polarity are arranged on one side surface of the solar cell; an electric field opposite to the first electrodes in polarity is arranged on the surface of the solar cell; the first conductive piece is electrically connected to the first electrodes; and the insulating layer is arranged between the surface of the solar cell and the first conductive piece. According to the invention, because the insulating layer is arranged between the back of the solar cell and the first conductive piece, short-circuiting caused by contacting the first conductive piece connected with the first electrodes and the electric field at the back of the cell and opposite to the first electrodes in polarity can be avoided; and therefore, industrial application of the back contact type solar cell component can be ensured.

Description

technical field [0001] The invention relates to a solar cell component and a manufacturing method thereof, in particular to a back contact solar cell component and a manufacturing method of the back contact solar cell component. Background technique [0002] A back contact solar cell (or called a back electrode solar cell) refers to a silicon solar cell in which the positive and negative electrodes of the cell are located on the back of the cell. Compared with the traditional silicon solar cell, since the main grid line is canceled on the front of the cell, the shading loss is reduced, thereby increasing the effective lighting area and improving the efficiency of the cell. In addition, because the positive and negative electrodes of the battery are located on the back of the battery, the connection and packaging of the battery are facilitated, and the manufacturing process is simplified; and because the busbars on the front of the battery are reduced, the battery looks more ...

AI Technical Summary

Problems solved by technology

[0003] If the back electric field is a positive electric field, in the manufacturing process of the back contact solar cell module, when the traditional electrical connection method is used to electrically connect adjacent cells in series, the electrical connection device connected to the negative electrode will inevitably be connected to the positive electrode. Electric field contact, thus causing a short circuit; if the back electric field is a negative electric field, when the traditional electrical connection method is used to electrically connect adjacent cells in series, the electrical connection device connected to the positive electrode will also inevitably contact the negative electric field, cause a short circuit
