A photovoltaic apparatus comprises:
an optical fiber core (202; 302);
a first electrode (204; 304) surrounding the optical fiber core (202; 302);
at least one photosensitive organic layer (208; 308; 312) surrounding the first electrode (204; 304) and electrically connected to the first electrode (204; 304); and
a second electrode (210; 314) surrounding the organic layer (208; 308; 312) and electrically connected to the organic layer (208; 308; 312),
characterised in that:
said first electrode (204;304) is radiation transmissive;
said photosensitive organic layer (208; 308; 312) comprises at least one upconverter material, anti-Stokes material, laser dye, anti-counterfeiting dye, quantum dot, or combination thereof; and either:
said second electrode (210; 314) is reflective; or
the apparatus comprises a reflective external metal contact surrounding said second electrode; or
said second electrode (210; 314) is reflective and the apparatus comprises a reflective external metal contact surrounding said second electrode. |
