Efficient Titanium Oxide/Conjugated Polymer Photovoltaics for Solar Energy Conversion

Record high efficiencies for a polymer-based solar cell are reported here for an inorganic/organic composite photovoltaic device containing a single polymer film rather than a polymer/polymer or polymer/nanoparticle blend. The high efficiencies are reported to be due to device construction (see Figure) and the electronic properties of the phenylamino-p-phenylenevinylene-based polymer used.
