20080302406 | Solar Cell Panel - Generally, solar cell panels are black, being inferior in design.

20160380140 | COLORLESS LUMINESCENT SOLAR CONCENTRATORS USING COLLOIDAL SEMICONDUCTOR NANOCRYSTALS - 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. | 12-29-2016 |
