SOLAR REVOLUTION – Solar Paint Ted Sargent is a pioneer in solar science. He’s operating on solar technology that could literally be woven into each and every aspect of everyday life, from our clothes to our roads, employing what is known as a spray-on solar cell. The implications for our power systems are profound. As Ted says, “Solar energy is not just an exciting science problem, but an extremely essential human problem.” Ted is working on solar nanotechnology with the prospective to make solar energy very low cost and permit society to collect it on a enormous scale. At the moment, solar technology fees far more to construct and install than most folks are willing to spend. Solar panels, for example, the technology most typically related with solar energy, are installed on your rooftop. The expense of collecting 1 kilowatt per hour of solar energy (about a third of the electricity an average household uses on any offered day) is about 000. Not only are panels expensive to install, they capture only the visible portion of the sun’s rays so they function only on sunny days. Ted’s focus is the infrared portion of the sun’s rays which accounts for far more than half of all solar energy. What’s more, infrared power is accessible to us even in cloudy weather. A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band holes) in all 3 spatial directions. The confinement can be due to …
