Abstract

The invention provides a back contact solar cell module production method and a back contact solar cell module, and relates to the technical field of solar photovoltaics. The back contact solar cell module production method comprises the steps of providing a conductive connection film, wherein the conductive connecting film comprises an adhesive layer and a wire group adhered to one side of the adhesive layer, the wire group comprises a plurality of wires which are arranged at intervals, and each wire comprises a wire body and a hot melting conducting layer located on the surface of the wire body; sequentially arranging the plurality of back contact solar cells in columns to obtain a back contact solar cell column; stacking the side, provided with the wire group, of the conductive connecting film on the back surface of the back contact solar cell sheet column to form a solar cell string precursor; and laminating the solar cell string precursor, a cover plate and a packaging film layer,so that the hot melting conductive layer is melted to be electrically connected with the wire body and an electrode of the back contact solar cell. According to the invention, the connection strengthof the wire group and the back contact solar cells is enhanced, and the positioning complexity is reduced.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a production method of a back-contact solar cell assembly and a back-contact solar cell assembly. Background technique [0002] Since the back contact solar cell module has no busbar on the front, the positive and negative electrodes are arranged on the back of the battery, which reduces shading, effectively increases the short circuit of the battery, improves the energy conversion efficiency of the module, and has broad application prospects. [0003] At present, the production method of back-contact solar cell modules is mainly as follows: laminate a conductive backsheet on the back of the back-contact solar cell sheet, combine the encapsulation material and cover material on the front of the back-contact solar cell sheet, the back-contact solar cell sheet, and the conductive backsheet laminated. [0004] In the production method of the above-mentioned back-contact...
