Abstract: Embodiments include photoactive regions of organic photovoltaic cells including an n-type dopant or a mixture of n-type dopants, one or more electron donor materials, and one or more electron acceptor materials. Embodiments further include n-type dopants, photoactive regions of organic photovoltaics comprising n-type dopants, methods of preparing photoactive regions comprising n-type dopants, organic photovoltaics comprising n-type doped photoactive regions, and the like.
