Scientists working with Natcore Technology in the Rice University laboratories of Prof. Andrew Barron, a Natcore co-founder, have successfully formed a heterojunction solar cell using germanium quantum dots on an ordinary n-type silicon wafer.
Scientists at VTT have developed a prototype of a tree that harvests solar energy from its surroundings – whether indoors or outdoors – stores it and turns it into electricity to power small devices such as mobile phones, humidifiers, thermometers and LED light bulbs. The technology can also be used to harvest kinetic energy from the environment.
Solar energy boosters have a lot to be happy about these days. The growth in their industry has been tremendous, so much so that proponents are now able to wave around some pretty impressive stats. Like this: There are now over 173,000 solar jobs in the United States.
