Polymer-free near-infrared photovoltaics with single chirality (6,5) semiconducting carbon nanotube active layers.
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-basedExpand
