Researchers at the UCLA Henry Samueli School of Engineering and Applied Science and UCLA's California Nanosystems Institute report that they have significantly enhanced polymer solar cells' performance by building a device with a new "tandem" structure that combines multiple cells with different absorption bands. The device had a certified power-conversion efficiency of 8.62 percent and set a world record in July 2011.
