High-Performance Solid-State PbS Quantum Dot-Sensitized Solar Cells Prepared by Introduction of Hybrid Perovskite Interlayer

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 TiO 2 (mp-TiO 2 ) by spin-assisted successive precipitation and anionic exchange reaction method do not exhibit PbSO 4 but have PbSO 3 oxidation species. By introducing perovskite interlayer in between mp-TiO 2 /PbS QDs and poly-3-hexylthiophene, the PbSO 3 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.
