Abstract
The present invention relates to organic optoelectronic devices and, in particular, to organic photovoltaic devices having a fiber structure. In one embodiment, a photovoltaic device comprises a first electrode comprising an indium tin oxide fiber, at least one photosensitive organic layer surrounding the first electrode and electrically connected to the first electrode, and a second electrode surrounding the organic layer and electrically connected to the organic layer.
Claims23
A photovoltaic apparatus comprising:
- an optical fiber core;
- a radiation transmissive first electrode surrounding the optical fiber core;
- at least one photosensitive organic layer surrounding the first electrode and electrically connected to the first electrode;
- and
- a second electrode fully enclosing the photosensitive organic layer and electrically connected to the photosensitive organic layer, wherein the organic layer comprises at least one upconverter material, anti-Stokes material, laser dye, anti-counterfeiting dye, quantum dot, or combination thereof,
- wherein (a) the second electrode is a continuous reflective metal layer having a thickness of about 100 nm to about 1 μm;
- or (b) the apparatus comprises a reflective and continuous external metal contact fully enclosing the second electrode;
- or (c) the second electrode is reflective and the apparatus comprises a reflective and continuous external metal contact fully enclosing the second electrode;
- and
- wherein the apparatus is operable to pass radiation into the photosensitive organic layer from the interior of the fiber core.
