THE WOODLANDS, Texas--(BUSINESS WIRE)--Evolution Solar (Pinksheets:EVSO). Researchers from the University of Texas in Austin and the University of Minnesota in Minneapolis have discovered a process that can be used to increase the conversion efficiency of solar cells up to 66%. The process transfers hot electrons from quantum dots to an electron acceptor. In typical semiconductor solar cells, photons with energies above the semiconductor’s bandgap generate hot electrons, and much of the energy from the hot electrons is lost through heat before it can be captured and used for electricity.
