“Efficient roll-to-roll fabrication is key to achieving the low-cost, high-volume production that would enable photovoltaics to scale to a significant fraction of global energy production,” explained He Yan, a collaborator from Hong Kong University of Science and Technology.

The team experimented with a coating material composed of a fluorinated polymer and a fullerene (also known as a “buckyball”). Going by the technical name PffBT4T-2OD, the polymer is attractive for scaled production—achieving a reported power conversion efficiency of more than 11 percent. Importantly, it can be applied in relatively thick layers—conducive to roll-to-roll processing.

“Real-time measurements were critical to developing a proper understanding of the film formation kinetics and ultimate optimization,” said Aram Amassian, a collaborator from Saudi Arabia’s King Abdullah University of Science and Technology.
