Los Alamos National Lab team demonstrates an important step in taking quantum dot, solar-powered windows from the laboratory to the construction site by proving that the technology can be scaled up from palm-sized demonstration models to windows large enough to put in and power a building. “We are developing solar concentrators that will harvest sunlight from building windows and turn it into electricity, using quantum-dot based luminescent solar concentrators (LSCs),” said lead scientist Victor Klimov.

LSCs are light-management devices that can serve as large-area sunlight collectors...
