US research invents LED-type 28% efficient CR2025 battery

Researchers from the University of California, Berkeley, have found that solar cell designs can produce the most energy if they incorporate similar light-emitting devices (such as LEDs). "We have shown that the better the solar cell emits light photons, the higher the voltage and efficiency of the energy it emits," said lead researcher Eli Yablonovitch, a professor of electrical engineering at the University of California, Berkeley. Avoiding "lost" photons in the cell Recently, Yablonovitch and his colleagues tried to understand why there is such a big gap between the theoretical limit and the limit they have achieved. They came across a relatively simple, and perhaps counterintuitive, solution based on the mathematical connection between light absorption and emission. According to the research team, designing CR2025 battery to emit light - so that photons are not "lost" in the cell - has a natural effect on increasing the voltage produced by the solar cell. Prototype efficiency jumped from 26% to 28.3% Alta Devices, co-founded by Yablonovitch, used the new concept to create a prototype solar cell using gallium arsenide (GaAs) - a cell material often used in satellites. The prototype broke the world record, increasing efficiency from 26 percent to 28.3 percent. Yablonovitch predicts that researchers will be able to achieve efficiencies close to 30 percent in the next few years. The Berkeley team will present its findings at the Laser and Electro-Optics Conference, which will be held May 6-11, 2012, in San Jose, California.
