Have such a window, it can provide a clear vision and illuminate the room, can use the sun to the building to provide an effective supply of electricity » According to the July 11 "Science" magazine reported that the U.S. Massachusetts Institute of Technology engineers to create a novel method for solar concentrators, this novel can imagine into reality.
Responsible for the study, associate professor of electrical engineering • Mark Bartholomew said that this new type of solar concentrators for use of a coating, in the large-scale (such as a window) to collect sunlight, and then gathered at the edge. In this way, does not require the entire roof covered with expensive solar cells, solar cells and simply Wai embedded in the flat glass plate on the edge, so that everyone will be able to collect solar energy increased 40 times over.
Before the solar concentrators are used for large mirror to track the movement of the sun condenser, and now the technology to avoid its disadvantages. The new system is very easy to create, because reducing the size of the solar cells and therefore reduce costs. The researchers believe that in three years to achieve commercialization, or even add to the existing solar system, but also with a minimum of 50 per cent of additional costs to improve efficiency, thus greatly reducing the cost of solar power.
The U.S. Department of Energy Office of the scientific basis of energy science program manager Alaweida • Gini believes that this innovative design without the need for optical tracking could be achieved under the conditions of the outstanding conversion of solar energy, which proved to be "in a cost-effective Use of solar energy "access to the leading results of a revolutionary, innovative research is the basis of essential importance.
