Dr. Aimee Tomlinson, associate professor of chemistry at the University of North Georgia (¹û¶³´«Ã½), has published a research paper in Polymer, the International Journal for the Science and Technology of Polymers.

The journal publishes original research on all areas of polymer science and technology with emphasis on molecular or intermediate-scale interpretations of data.

The published paper focuses on organic photovoltaic (OPV) devices, which are very similar to current solar cells, but removes many of the expensive metals from the device, and therefore makes them much cheaper.

"Our research was meant to see how changing out a single atom in a polymer sub-unit would impact the material’s performance in a solar cell.  In the end, we wanted to know how the nitrogen version of a well-known polymer would fare in a solar cell," said Tomlinson. 

Tomlinson’s co-authors are Benjamin J. Hale, Malika Jefferies-EL, Jon Stoffer, Moneim Elshobaki, Ryan Gebhardt, and Sumit Chaudhary from Iowa State University; and David Wheeler, chemistry student from ¹û¶³´«Ã½.
