Researchers develop solar battery that is easy to produceA local research team has developed a hybrid solar battery that costs one-third as much as existing sun-powered batteries that is also the most energy efficient in the world.
Silicon-based solar batteries have been commercialized, but the cost of production has been too high to compete against cheap fossil fuel-powered electricity.
The team led by Seok Sang-il, a professor of Sungkyunkwan University and researcher at the Korea Research Institute of Chemical Technology, received recognition from the U.S. National Renewable Energy Laboratory for having about 18 percent energy efficiency, the highest of its kind. The professor said that the battery, made with thin “perovskite films,” can be as cheap as fossil-fuel electricity, because it is easy to manufacture.
