Patent ID: 7884280

Claim:
A solar cell comprising: (a) a first substrate comprising a first electrode; and (b) a layer of light harvesting rods electrically coupled to a surface portion of said first electrode, said light harvesting rods comprising a non-discotic backbone polymer of porphyrinic macrocycles coupled to said surface portion by an end terminal thereof, wherein said polymer comprises monomeric units of porphyrinic macrocycles; and wherein said non-discotic backbone polymer is a crosslinked polymer; and (c) a second substrate comprising a second electrode, with said first and second substrate being positioned to form a space therebetween, and with at least one of (i) said first substrate and said first electrode and (ii) said second substrate and said second electrode being transparent; wherein said non-discotic backbone polymer comprises a crosslink produced by reaction of an amine group with an isothiocyanate group, an acid hydrazide group with a formyl group, or a metal reagent with coordinating groups; and wherein said first and second substrate each comprise an organic polymer.
