Material’s Structure Hints at More Efficient Solar Cell

Facebook X LinkedIn Email
UPTON, N.Y., April 27, 2012 — New details about the structure of one of the most efficient photovoltaic materials could inform the synthesis of new materials with even better properties. PCDTBT, one of the best known organic photovoltaic materials, converts sunlight to electricity with a 7.2 percent efficiency, but the reasons why were a mystery. “Despite the fact that this material has been extensively studied, no one has reported detailed structural features to provide a basis for its superior performance,” said Brookhaven National Lab physicist Benjamin Ocko, who led the current research....Read full article
