Abstract
A solar cell incorporates a light harvesting array that comprises: (a) a first substrate comprising a first electrode; and (b) a layer of light harvesting rods electrically coupled to the first electrode, each of the light harvesting rods comprising a polymer of Formula I:X1&Parenopenst;Xm+1)m  (I)wherein m is at least 1, and may be from two, three or four to 20 or more; X1 is a charge separation group (and preferably a porphyrinic macrocycle, which may be one ligand of a double-decker sandwich compound) having an excited-state of energy equal to or lower than that of X2; and X2 through Xm+1 are chromophores (and again are preferably porphyrinic macrocycles).
