Abstract

The invention provides a solar cell module and a production method thereof, and relates to the technical field of solar photovoltaics. The solar cell module comprises a plurality of p-type crystallinesilicon solar cells and a plurality of wire groups used for connecting the adjacent p-type crystalline silicon solar cells. Each wire group comprises a preset number of wires which are arranged in parallel; the preset number is 4-30; the wire comprises a baseline; and the wire further comprises a hot melting conducting layer which at least wraps the surface of the base wire. The hot melting conducting layer comprises a first hot-melt conductive layer for hot-pressing connection or viscous connection with a front metal electrode of a p-type crystalline silicon solar cell, and a second hot-meltconductive layer for hot-pressing connection or viscous connection with a back metal electrode of another adjacent p-type crystalline silicon solar cell; and the width of the wire is larger than or equal to 50 micrometers and smaller than or equal to 1000 micrometers. According to the invention, the assembly loss is reduced, the current transmission loss is reduced, and the photoelectric conversion efficiency is high.

Description

Technical field[0001]The present invention relates to the field of solar photovoltaic technology, in particular to a solar cell component and a method for producing a solar cell component.Background technique[0002]The role of solar cell components is to convert solar energy into electrical energy, or send it to storage batteries for storage, or to drive loads.[0003]At present, the structure of the solar cell module is mainly as follows: a plurality of single solar cells are welded into a battery string by welding ribbon, and then packaged into a battery module that can output power.[0004]The above-mentioned solar cell module formed by ribbon welding has a large assembly loss.Summary of the invention[0005]The present invention provides a solar cell module and a solar cell module production method, which aims to solve the problem of large assembly loss of the solar cell module.[0006]According to a first aspect of the present invention, there is provided a solar cell module, including:...
