Disclosed herein are embodiments of a composition comprising a polymer or sol-gel and one or more nanocrystals. The composition is useful as a luminescent solar concentrator. The nanocrystals are dispersed in the polymer or sol-gel matrix so as to reduce or substantially prevent nanocrystal-to-nanocrystal energy transfer and a subsequent reduction in the emission efficiency of the composition. In some embodiments, the polymer matrix comprises an acrylate polymer. Also disclosed herein is a method for making the composition. Devices comprising the composition are disclosed. In some cases the polymer is the waveguide, in others the polymer is applied as a coating on a waveguide. In some examples, the device is a window.

An impact-resistant, photovoltaic (IRPV) window system is provided. The system may include an IRPV window coupled to a structure, a controller, and an insurance computing device. The IRPV window may include an impact resistant (IR) layer, a photovoltaic (PV) material that may generate an electrical output, and an electrode coupled to the PV material that may receive the electrical output. The IRPV window may permit a portion of visible light to pass through the IRPV window. The controller may monitor the electrical output and generate a solar profile of the structure based upon the electrical output. The insurance computing device may receive the solar profile and determine if an insurance policy associated with the structure is eligible for a policy adjustment and/or an insurance reward or discount offer.
