Organic multilayered photocell with enhanced separation of charges at polarization double barriers

At the interfaces of three-layered molecular structure of donor-absorber-acceptor (D-M-A) the polarization double barriers (PDB) may be formed due to a large difference in polarization energies of charge carriers in each layer: PD,PA ⪡ PM. Such PDBs are originated from solid state effect of intermolecular interactions. Properly designed PDB at account of single molecular properties of D,A and M layers may lead to selective separation of photogenerated charge carriers enhancing the efficiency of D-M-A photocell.
