Patent ID: 7858973

Claim:
An electrically conducting polymer composite p-n junction, comprising: an electron-doped, n-type polymer composite layer comprising a first polymer material and a plurality of electrically conductive particles dispersed and imbedded therein; and a hole-doped, p-type polymer composite layer comprising a second polymer material and a plurality of carbon nanotubes (CNTs) dispersed and imbedded therein, the p-type polymer composite layer being disposed in contact with the n-type polymer composite layer; wherein the first polymer in the n-type composite polymer layer and the second polymer in the p-type composite polymer layer are each comprised of at least one material selected from the group consisting of polyethylene-ethylene glycol (PE-EG), polyethylene terephthalate (PET), silicone, epoxy resin, anaerobic glue, and acrylic glue.
