Scientists demonstrate a house window that doubles as a solar panel thanks to recent quantum-dot technology. Isn’t this just so convenient?

This solar panel window project demonstrates that superior light-emitting properties of quantum

dots can be applied in solar energy by helping more efficiently harvest sunlight

Los Alamos National Laboratory researchers in collaboration with scientists from University of Milano-Bicocca (UNIMIB), Italy demonstrate a house window that doubles as a solar panel thanks to recent quantum-dot technology.

The work has been published as ‘Large-area luminescent solar concentrators based on ‘Stokes-shift-engineered’ nanocrystals in a mass-polymerized PMMA matrix,’in the online journal Nature Photonics.

“The key accomplishment is the demonstration of large-area luminescent solar concentrators that use a new generation of specially engineered quantum dots,” said lead researcher Victor Klimov of the Center for Advanced Solar Photophysics (CASP) at Los Alamos.

Quantum dots are ultra-small bits of semiconductor matter that can be synthesized with nearly atomic precision via modern methods of colloidal chemistry. Their emission color can be tuned by simply varying their dimensions. Color tunability is combined with high emission efficiencies approaching 100 percent. These properties have recently become the basis of a new technology – quantum dot displays – employed.
