    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.

    Abstract: A light redirecting film defining a longitudinal axis, and including a base layer, an ordered arrangement of a plurality of microstructures, and a reflective layer. The microstructures project from the base layer, and each extends across the base layer to define a corresponding primary axis. The primary axis of at least one of the microstructures is oblique with respect to the longitudinal axis. The reflective layer is disposed over the microstructures opposite the base layer. When employed, for example, to cover portions of a PV module tabbing ribbon, or areas free of PV cells, the films of the present disclosure uniquely reflect incident light.

    Abstract: A light redirecting film includes a first layer disposed on a second layer with structured major surfaces of the first and second layers facing each other. An optically reflective layer or a metal layer is disposed between the first and second layers. The first layer can be a hot melt adhesive layer and the second layer can be a polymeric layer. The first and second layers can be unitary layers. The first layer can be a first polymeric layer having a softening temperature T1 and the second layer can be a second polymeric layer having a softening temperature T2 greater than T1. Heating and/or applying pressure to the film changes an optical characteristic of the film by less than about 5%.
