Los Alamos Center for Advanced Solar Photophysics researchers hold a large prototype solar window.

In these devices the light, transmitted through the window, it is absorbed by nanoscopic particles (semiconductor quantum dots) dispersed in the glass window. These quantum dots absorb light at the infrared wavelength, invisible to the human eye and guide these waves of light towards a solar cell at the edge of the window.
Using this design, an almost transparent window becomes an electric generator, that can power the air conditioner of your room on a hot day or a stove on a cold day.
