Reflective solder strip, photovoltaic module and preparation method

The invention provides a reflective solder strip, a photovoltaic module and a preparation method, and belongs to the technical field of photovoltaic modules. A reflective solder strip is used for being welded with two adjacent battery pieces, and the reflective solder strip comprises a base band and a coating on the surface of the base band; the base band comprises a first segment and a second segment; a first subsection is provided with a first reflecting surface for reflecting sunlight and a lower plane welded with the top surface of one battery piece, and a second subsection is provided with a second reflecting surface for reflecting sunlight and an upper plane welded with the bottom surface of the other battery piece. According to the reflective solder strip, the photovoltaic module and the preparation method, the section of the reflective solder strip is pentagonal, and two reflecting surfaces are arranged towards the sunlight surface; when the solar cell module is horizontally placed, the two reflective
