Harry Atwater and Colleagues Create Highly Absorbing, Flexible Solar Cells with Silicon Wire Arrays

Harry A. Atwater, Jr., Howard Hughes Professor and Professor of Applied Physics and Materials Science, and his colleagues have created highly absorbing, flexible solar cells with silicon wire arrays. "These solar cells have, for the first time, surpassed the conventional light-trapping limit for absorbing materials," says Professor Atwater. Furthermore this new type of flexible solar cell uses only a fraction of the expensive semiconductor materials required by conventional solar cells. [Caltech Press Release]
