Rubrene crystal raises hope for the use of organic semiconductors and cheaper, more efficient solar cells Rutgers University physicists have found new properties within a material that could lead to the production of less expensive and more efficient plastic solar cells. Vitaly Podzorov, co-author of the study and assistant professor of physics at Rutgers University, along with his research team have discovered that organic semiconductors allow energy-carrying particles -- which are created by "packets" of light -- to journey a thousand times farther than researchers previously thought. "Organic semiconductors are promising for solar cells and other uses, such as video displays, because they can be...
