Abstract
A photovoltaic device includes a photoactive region disposed between and electrically connected to two electrodes where the photoactive region includes photoactive polymer-wrapped carbon nanotubes that create excitons upon absorption of light in the range of about 400 nm to 1400 nm.
Claims27
A device comprising:
- a first electrode;
- a second electrode;
- and
- a photoactive region disposed between and electrically connected to the first electrode and the second electrode,
- wherein the photoactive region comprises a photoactive substantially semiconducting polymer-wrapped carbon nanotubes disposed within an organic semiconductor material, whereby the organic semiconductor material and the photoactive substantially semiconducting polymer-wrapped carbon nanotubes form a bulk heterojunction layer,
- wherein the carbon nanotubes themselves are photoactive.
