摘要

The present application relates to the field of solar cells, and provided therein are a back-contact solar cell conductive composite board and a preparation method therefor, a back-contact solar cell interconnection structure, and a double-sided back-contact solar cell assembly, which may solve the problem of fragmentation caused to the assembly during lamination. The conductive composite board comprises a conductive connection layer and a base layer made of a thermoplastic material, the conductive connection layer being embedded in the base layer made of the thermoplastic material; and the conductive connection layer comprises a plurality of conductive metal wires and a bus bar connected to the conductive metal wires, the conductive metal wires being used for electrical connection with a back electrode of the back-contact solar cell panel. The beneficial effects of the present application are as follows: the conductive composite board provided by the present application has a simple structure and low costs, is easily cut into various sizes and shapes, is convenient for use in combination with various back panels, and has flexible scenarios of application; when used for connection with back-contact solar cells, the conductive composite board has the advantages of being highly efficient, resistant to hidden cracks, and capable of achieving thin cells, thereby reducing costs and being suitable for a variety of solar cell structures, such as MWT, EWT, and IBC.
