Embodiments described herein provide functionalized carbon nanostructures for use in various devices, including photovoltaic devices (e.g., solar cells). In some embodiments, carbon nanostructures substituted with at least one cyclobutyl and/or cyclobutenyl group are provided. Devices including such materials may exhibit increased efficiency, increased open circuit potential, high electron/hole mobility, and/or low electrical resistance.

An electrically conductive polymer linked to conductive nanoparticle is provided. The conductive polymer can include conductive monomers and one or more monomers in the conductive polymer can be linked to a conductive nanoparticle and can include a polymerizable moiety so that it can be incorporated into a polymer chain. The electrically conductive monomer can include a 3,4-ethylenedioxythiophene as a conductive monomer. The electrically conductive polymer having the conductive nanoparticle can be prepared into an electrically conductive layer or film for use in electronic devices.
