description The utility model discloses a base film for a solar cell backboard, and relates to the technical field of photovoltaic modules. The base film for the solar cell back plate comprises a transmission film layer, a first electrode layer and a second electrode layer, the reflection structure layer is arranged on one side of the transmission film layer; wherein the reflection structure layer is a micro-lens structure which is sequentially arranged along the plane of the transmission film layer in an array mode, the diameter of the micro-lens structure is 40-60 micrometers, and the height of the micro-lens structure is 20-30 micrometers. According to the utility model, the problems that in the prior art, a prism structure is adopted to reflect light rays, and the prism structure can only reflect light rays perpendicular to the prism direction and cannot reflect light rays parallel to the prism direction, so that the reflection efficiency of the solar cell backboard is low, and the application range of the base film
