College of southern California scientists show us a more efficient use of graphene solar panels

A University of Southern California team has produced flexible transparent carbon atom films that may have great potential for a new breed of solar cells.

Inside a paper recently published in the journal ACS Nano, researchers stated that organic photovoltaic (OPV) cells have been proposed as a means to achieve cheap energy due to their ease of manufacture, light-weight, and compatibility with flexible substrates.

This work indicates that graphene, an extremely conductive and highly transparent type of carbon made up of atoms-thick sheets of carbon atoms, has high potential to fill this role.
