Abstract

Disclosed is a solar cell module, which comprises a solar cell module comprising a light transmitting element, a front encapsulant layer, a plurality of solar cells spaced from each other, a back encapsulant layer, and an encapsulation backsheet disposed in the module's thickness direction, the plurality of solar cells together forming a matrix which comprises a plurality of solar cell strings parallel with each other, each solar cell string being made up of a plurality of solar cells connected in series, there being a string gap formed between every two adjacent solar cell strings, and there being a cell gap formed between adjacent solar cells in each solar cell string, wherein the solar cell module further comprises a plurality of light redirecting films each of which comprises an optical structure, the light redirecting films being disposed on the solar cells' back surfaces opposite to their light receiving surfaces or the encapsulation backsheet's surface within the solar cell module, such that they spatially correspond to the string gaps and/or the cell gaps, and the optical structures being disposed to face the solar cell's back surfaces, such that the optical structures reflect light toward the interface between the light transmitting element and air, and the light is subsequently totally internally reflected back to the light receiving surfaces of the solar cells.
