#ENERGY: "Quantum Dots Enable Windows to Harvest Solar Energy"

The windows of the future could double as solar energy concentrators according to researchers at Los Alamos Natl. Lab which recently demonstrated a prototype: R. Colin Johnson @NextGenLog


Transparent quantum-dot-impregnated window panes luminescence under ultraviolet illumination.

Solar energy is collected by cadmium-selenium (CdSe) quantum dots which pass the energy to a cadmium-sulfur (CdS) inner cores which emits the light at a different wavelength thus concentrating the solar energy from the whole windows surface on the phovoltaic cells around the window's edge.
