- Abstract
- A Sb2(S1-x/Sex)3 graded-composition is obtained by a sequential deposition of Sb2S3 and Sb2Se3 onto a mesoporous TiO2 photoelectrode followed by thermal annealing at 300 °C. The compositional graded-solar cells exhibit a greatly enhanced performance compared to pristine Sb2S3-sensitized or Sb2Se3-sensitized solar cells. The best performing cell, delivering an incident-photon-to-current efficiency extended to 1050 nm, exhibits an overall power conversion efficiency of 6.6% under simulated illumination.
