Transparent, Near-infrared Luminescence Solar Concentrator for Power Generating Windows

A visibly transparent luminescent solar concentrator (LSC) is disclosed. The LSC includes a transparent substrate having at least one edge surface. A dye layer is coupled to the substrate, the dye layer having a peak absorption wavelength outside the visible band, the dye layer being configured to re-emit light at a peak emission wavelength outside the visible band, at least a portion of the re-emitted light being waveguided to the edge surface of the substrate. A photovoltaic device is coupled to the edge surface of the transparent substrate, the photovoltaic device being configured to absorb light at the peak emission wavelength and generate electrical energy.
