Fullerenes bridge conductive gap in organic photovoltaics: Efficient cathode interlayers made of ionene polymers refined with pendant fullerenes

In contrast to common silicon-based solar cells, organic photovoltaics (OPVs) involve organic molecules in solar power generation. Materials in OPVs are abundant and processable, cheap and lightweight, and the modules can be made flexible and with...
