NOVELTY - A photovoltaic module comprises a back sheet (3), a front sheet (1), a photovoltaic cells layer (2), conductive pathways, and an electrical output. The front sheet comprises a glass sheet, a multi-layer fluoropolymeric film (4), and an adhesive layer. The multi-layer fluoropolymeric film comprises a first fluoropolymeric layer comprising a first fluoropolymer, and a second fluoropolymeric layer comprising a second fluoropolymer.    USE - A photovoltaic module used for a photovoltaic array (claimed) used in solar energy applications.    ADVANTAGE - The photovoltaic module provides improved efficiency and durability of thermal solar installations.    DETAILED DESCRIPTION - A photovoltaic module comprises a back sheet (3), a front sheet (1), a photovoltaic cells layer (2) between the front sheet and the back sheet, conductive pathways to combine the electrical output of the photovoltaic cells to an electrical output from the module, and an electrical output to interconnect the module with other modules to form a photovoltaic array, or with an external electrical load. The back sheet, front sheet, and the photovoltaic cells layer are laminated together. The front sheet comprises a glass sheet having a front surface, a multi-layer fluoropolymeric film (4) on the front surface, and an adhesive layer between the front surface and the multi-layer fluoropolymeric film. The multi-layer fluoropolymeric film comprises a first fluoropolymeric layer having a refractive index of 1.45-1.5 and a thickness of greater than 10 mu m, and comprising a first fluoropolymer; and a second fluoropolymeric layer having a refractive index of 1.33-1.37 and a thickness of 100-150 nm, and comprising a second fluoropolymer; where the reflectance spectrum of the multi-layer fluoropolymeric film exhibits minimum in the wavelength of 400-1100 nm. An INDEPENDENT CLAIM is included for illuminating a photovoltaic module.    DESCRIPTION OF DRAWING(S) - The drawings are schematic side view and top-down view of the photovoltaic module.
