BACK-CONTACT SOLAR CELL CONDUCTIVE COMPOSITE BOARD AND PREPARATION METHOD THEREFOR, BACK-CONTACT SOLAR CELL INTERCONNECTION STRUCTURE, AND DOUBLE-SIDED BACK-CONTACT SOLAR CELL ASSEMBLY

摘要

The application provides a back-contact solar-cell conductive composite panel and preparation method therefor, a back-contact solar-cell interconnection structure and a double-sided back-contact solar-cell module during lamination. The conductive composite panel includes a conductive connection layer and a base layer made of a thermoplastic material, and the conductive connection layer is embedded in the base layer made of the thermoplastic material; and the conductive connection layer includes a plurality of conductive metal wires and a bus bar connected to the conductive metal wires, and the conductive metal wires are configured for being electrically connected to a back electrode of a back-contact solar-cell sheet. The beneficial effects of the application are as follows: the conductive composite panel provided by the application has simple structure and low cost; and is easily cut into various sizes and shapes, is convenient for use in combination with various back panels, and has flexible application scenarios; when configured for connection with the back-contact solar cell, the conductive composite panel has the advantages of being highly efficient, resistant to hidden cracks, and capable of achieving thin cells, thereby reducing cost and being suitable for a variety of solar cell structures such as MWT, EWT, and IBC.
