| Abstract
| - It is suggested that attaching chromopores to a conducting polymer chain anchored to a semiconductor surfaceis a good strategy for development of dye-sensitized solar cells. A model system that illustrates this principleis constructed by bonding mercurochrome to poly(vinyl alcohol) films adsorbed onto nanocrystalline TiO2films. The dye−polymer structure enables transport of electrons (released in excitation of the dye) along thepolymer chain to TiO2 as states in the lowest unoccupied molecular orbital of the polymer. By attachingseveral chromopores to a polymer chain, panchromatic sensitization can be achieved in principle by avoidingconcentration quenching and the insulation by thick dye layers.
