Tweaking quantum dots powers-up double-pane solar windows

(DOE/Los Alamos National Laboratory) Researchers at Los Alamos National Laboraotry are creating double-pane solar windows that generate electricity with greater efficiency and also create shading and insulation. It's all made possible by a new window architecture which utilizes two different layers of low-cost quantum dots tuned to absorb different parts of the solar spectrum. The approach complements existing photovoltaic technology by adding high-efficiency sunlight collectors to existing sola
