io9 reports on A Single Breakthrough That Could Cut Costs on Solar Energy by 25% "A group of chemists at Ohio State University has invented a solar panel that stores energy without an external battery. The self-contained tuner/capacitor panels are already being licensed to industry."
"The invention also solves a longstanding problem in solar energy efficiency, by eliminating the loss of electricity that normally occurs when electrons have to travel between a solar cell and an external battery. Typically, only 80 percent of electrons emerging from a solar cell make it into a battery. With this new design, light is converted to electrons inside the battery, so nearly 100 percent of the electrons are saved."
