Scientists invent double-pane solar windows powered by quantum dots

scientists invent double panel solar windowsResearchers at the Los Alamos National Laboratory have designed efficient and cost-effective solar windows by combining quantum dot technology with a double pane structure.

The layers of quantum dots are tweaked to absorb only part of the solar spectrum, allowing the double-pane solar windows to generate energy while providing shade and insulation.

Scientists suggest the new technology will lower the cost of solar electricity.

"The approach complements existing photovoltaic technology by adding high-efficiency sunlight collectors to existing solar panels or integrating them as semitransparent windows into a building's architecture," lead researcher Victor Klimov said in a news release.

The new windows rely on a technology called "solar-spectrum splitting," which allows the panels to simultaneously absorb lower- and higher-energy solar photons. The technology prevents reabsorption, a phenomenon that diminishes panels' electrical output.
