Abstract

original image

A solid-state dye-sensitized solar cell with 7.4% efficiency is fabricated by J. H. Kim and co-workers using meso/macroscopic, honeycomb-like, organized TiO2 photoanodes. These electrodes have dual pores, high porosity, good interconnectivity, and excellent light scattering properties. On page 3901, an approach to control these structures via a onestep self-assembly of preformed TiO2 nanocrystals and graft copolymers is presented.
