Double-Paned Solar Windows Crank Up Efficiency

Researchers at the Los Alamos National Laboratory (LANL), USA, led by OSA Fellow Victor Klimov, have devised a prototype large-area (230-cm2) solar window that cleverly combines a double-paned architecture and cheap-to-manufacture quantum dots (QDs) to boost solar energy collection efficiency compared with single-pane models (Nat. Photon., doi: 10.1038/s41566-017-0070-7). The key to the scheme: engineering the QDs embedded in the upper and lower panes to capture and rechannel photons from different parts of the solar spectrum—and to keep re-absorption of photons to a minimum.
