摘要：

We report fabrication of a TiO2 interconnected network structure for photovoltaic applications, which was obtained using polystyrene-block-polyethylene oxide diblock copolymer as the templating agent. The synthetic method is simple and highly reproducible. The pore size of the structure is controlled by the amount of Ti precursor provided. The heterojunction solar cells consisting of a TiO2 porous network structure and poly (2-methoxy-5-(2(')-ethyl-hexyloxy)-p-phenylene vinylene) (MEH-PPV) showed improved performance with a short circuit current of 3.25 mA/cm(2) under AM 1.5 solar illumination. The achieved maximum external quantum efficiency for optimum MEH-PPV thickness was 34%. (c) 2005 American Institute of Physics.
