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.
