Abstract

The present invention provides a solar cell module, which comprises: a back panel, a rear package layer, a plurality of mutually spaced solar cells, a front package layer, and a light-transmissive element, which are successively disposed along a thickness direction of the solar cell module. The solar cell module further comprises at least one light redirecting film, each light redirecting film comprising an optical structure layer. The light redirecting film is disposed on a surface, opposite to the side where the solar cells are located, of the rear package layer; the position of the light redirecting film corresponds to a region between the solar cells. The optical structure layer faces the rear package layer, such that the optical structure layer reflects the light towards an interface between the light-transmissive element and the air; and the light is then totally internally reflected to light-facing surfaces of the solar cells. The solar cell module has high electricity generation efficiency, and is further optimized in optical gain, electrical insulation property, and thermal/mechanical stress properties.
