A solar concentrator device is provided. The solar concentrator device includes a waveguide having a luminophore and a first refractive index; a photovoltaic component operably coupled to the waveguide; and a film disposed onto a surface of the waveguide, the film having a second refractive index. The second refractive index of the film is lower than the first refractive index of the waveguide. The waveguide and the film are visibly transparent.
