We demonstrate a polymer‐free carbon‐based photovoltaic device that relies on exciton dissociation at the SWNT/C 60 interface, as shown in the figure. Through the construction of a carbon‐based photovoltaic completely free of polymeric active or transport layers, we show both the feasibility of this novel device as well as inform the mechanisms for inefficiencies in SWNTs and carbon based solar cells.
