NOVELTY - Fabricating semiconductor structure comprises: providing nanorods (106) and photoresponsive nanocrystals (109) capped with first capping agent; exposing nanorods or nanocrystals to second bifunctional capping agent; combining nanocrystals with nanorods; combining bound nanorods and nanocrystals with functionalized monomer having a binding group, where the binding group exhibits strong affinity for the nanocrystals and weaker affinity for nanorods than bifunctional capping agent, where the monomer displaces first capping agent; and polymerizing the monomer.    USE - The method is useful to fabricate the semiconductor structure having heterojunctions that is useful in photovoltaic cell (claimed), preferably nanorod-nanocrystal-polymer hybrid solar cell.    ADVANTAGE - The method: provides photovoltaic cell with small particles (nanocrystals) that serve as light-absorbing material and heterojunctions at which the excited electron-hole pairs (i.e. excitons) split, thus reducing recombinations, and exhibiting higher conversion efficiency of photons into electricity and mechanical flexibility at low cost; and exhibits controlling over binding of polymer to nanorod resulting in substantial losses in efficiency due to recombination.    DETAILED DESCRIPTION - Fabricating a semiconductor structure having heterojunctions for use in a photovoltaic cell (100), comprises: providing many nanorods (106) and photoresponsive nanocrystals (109) capped with a first capping agent; exposing the nanorods or nanocrystals to a second bifunctional capping agent; combining the nanocrystals with nanorods, where the nanocrystals bind to nanorods via bifunctional capping agent; combining the bound nanorods and nanocrystals with a functionalized monomer having a binding group, where the binding group exhibits strong affinity for the nanocrystals than the first capping agent and weaker affinity for nanorods than the bifunctional capping agent, where the monomer preferentially displaces the first capping agent to bind to the nanocrystals but not to the nanorods; and polymerizing the monomer.
