Polymer-Fullerene BHJ Blends

In addition, polymers can also be chemically linked with the inorganic nanocrystals for improved charge transfer from polymer to inorganic 

Miller et al reported a composite from a water soluble multiwalled carbon nanotube (MWNT) and polythiophene for bilayer organic solar cells. This composite layer was then combined with C in bilayer structure. Incorporation of MWNTs into the polythiophene increased the FF by 20% with a corresponding improvement of efficiency compared to the polythiophene/CgQ bilayer device containing no MWNTs [144]. As the
