Abstract

We have fabricated antimony sulfide (Sb ₂S ₃) sensitized nano-structured solar cells prepared by chemical bath deposition. By incorporating a surface treatment on the antimony sulfide films, an improvement in solar cell performance is observed. The influence of the TiO ₂ photoanode structure on solar cell efficiencies is also studied by varying the TiO ₂ nanoparticle size. Although smaller nanoparticle size provides a much larger effective surface area for sensitizer attachment, the smaller pore size lead to an over-aggregation of Sb ₂S ₃ particles on the surface pores. Devices fabricated on particles of size ∼100 nm exhibited an efficiency of 2.3.
