UChicago-Argonne National Lab Team Improves Solar Cell Efficiency

UChicago-Argonne National Lab Team Improves Solar Cell Efficiency

New light has been shed on solar power generation using devices made with polymers, thanks to a collaboration between scientists in the University of Chicago’s chemistry department, the Institute for Molecular Engineering, and Argonne National Laboratory. This polymer solar cell consists of a new polymer, called PID2, which was developed in the laboratory of Luping Yu, professor in chemistry at the University of Chicago. The new polymer improves the efficiency of electrical power generation by 15 percent when added to a standard polymer-fullerene mixture. Credit: Andrew Nelles Researchers identified a new polymer — a type of large molecule that forms plastics and other familiar materials — which improved the efficiency of solar cells. The group also determined the method by which the polymer improved the cells’ efficiency. The polymer allowed electrical charges to move mor...
