An energy harvesting system is provided. The energy harvesting system includes a waveguide, a luminophore embedded in the waveguide, and a solar photovoltaic array or a solar photovoltaic cell coupled to the waveguide. The energy harvesting system is visibly transparent, having an average visible transmittance of greater than about 50% and a color rendering index of greater than about 80 at normal incidence to the waveguide.
