Abstract

High-performance solid-state PbS quantum dot-sensitized solar cells (QD-SSCs) with stable 9.2% power conversion efficiency at 1 Sun condition are demonstrated by introduction of hybrid perovskite interlayer. The PbS QDs formed on mesoscopic TiO₂ (mp-TiO₂) by spin-assisted successive precipitation and anionic exchange reaction method do not exhibit PbSO₄ but have PbSO₃ oxidation species. By introducing perovskite interlayer in between mp-TiO₂/PbS QDs and poly-3-hexylthiophene, the PbSO₃ oxidation species are fully removed in the PbS QDs and thereby the efficiency of PbS QD-SSCs is enhanced over 90% compared to the pristine PbS QD-SSCs.
