摘要
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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
