The solar panel converts one photon in the two electrons


19/04/2013

Modern solar panels are a number of functional deficiencies. For example, if the photon energy is too low, the panel will not be able to absorb all his energy, and if it is too high, the extra energy will be spent on the excess heat. Be that as it may, the silicon panel can not generate more than one electron from a photon. This imposes severe limitations on the efficiency of photovoltaic panels, forcing scientists to seek possible solutions.

Researchers from the Massachusetts Institute of Technology, published a paper with the problem of increasing the efficiency of solar panels, which is based on pentacene organic dye. In the journal Science, they described the photovoltaic panels on pentacene, which generates two electrons from one photon, which allows you to generate more electricity and increase efficiency. Scientists in the past have expressed the theory that it might work, but this article is a testament to their ideas.

Scientists believe Pentacene coating for silicon panels will increase the efficiency with advanced 25% to 30%. This technology could be the next step in the development of solar panels. If successful, this would be a major breakthrough in the field of renewable energy.
