Empa Researchers Select DuPont's PI Film to Develop Efficient Building-integrated Photovoltaics

SpecialChem - Jun 14, 2011

DuPont™ Kapton® colorless polyimide film, a new material currently in development for use as a flexible superstrate for cadmium telluride (CdTe) thin film photovoltaic (PV) modules, has enabled a new world record for energy conversion efficiency. A team at Empa, the Swiss Federal Laboratories for Materials Science and Technology, has demonstrated a conversion efficiency of 13.8 percent using the new colorless film, leapfrogging their previous record of 12.6 percent and nearing that of glass. CdTe Solar Module with PI Film Because Kapton® film is over 100 times thinner and 200 times lighter than glass typically used for PV, there are inherent advantages in transitioning to flexible,...
