Back contact photovoltaic module and preparation method thereof

The invention provides a back contact battery photovoltaic module and a preparation method, relates to the technical field of photovoltaic, and can effectively solve the problem of fragments of the module in the lamination process and improve the efficiency of the module. The photovoltaic module comprises a front plate, a front adhesive film, a battery string, an insulation flexible buffer body, a back adhesive film and a rear plate, the transparent insulation flexible buffer body is arranged in a battery piece overlapping area, the fall space of battery overlapping can be effectively filled, the area is protected, subfissure and fragment defects of the battery pieces are avoided, gap areas of the battery pieces in the prior art are eliminated, and the service life of the battery pieces is prolonged. Therefore, the consistency of the appearance of the module is improved, the problem that decorative film materials are introduced to maintain the consistency of the appearance of the module at intervals is avoide
