Abstract

A Sb₂(S_1-x/Se_x)₃ graded-composition is obtained by a sequential deposition of Sb ₂S₃ 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 Sb₂Se ₃-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.
