title: High efficiency quantum dot heterojunction solar cell using anatase (001) TiO2 nanosheets.
abstract: This is the first report of using anatase TiO(2)  nanosheets with exposed (001) facets in a high-efficiency PbS quantum dot/TiO(2)  heterojunction solar cell. The TiO(2)  nanosheets have higher conduction band, and surface energy compared to normal anatase (101) TiO(2)  nanoparticles. This PbS QD/TiO(2)  heterojunction solar cell produces power conversion efficiency of 4.7% which is one of the highest reported in literature.
