New Solar Cell Technology Greatly Boosts Efficiency

Posted on Jun 9, 2011 in Uncategorized

With the creation of a 3-D nanocone-based solar cell platform, a team led by Oak Ridge National Laboratory’s Jun Xu has boosted the light-to-power conversion efficiency of photovoltaics by nearly 80 percent. The technology substantially overcomes the problem of poor transport of charges generated by solar photons. These charges — negative electrons and positive holes — typically become trapped by defects in bulk materials and their interfaces and degrade performance. “To solve the entrapment problems that reduce solar cell efficiency, we created a nanocone-based solar...
