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.

通过引入混合钙钛矿中间层制备的高性能固态PbS量子点敏化太阳能电池

通过引入混合钙钛矿中间层，证明了在1 Sun条件下具有稳定9.2％功率转换效率的高性能固态PbS量子点敏化太阳能电池（QD-SSC）。通过自旋辅助连续沉淀和阴离子交换反应方法在介观TiO ₂（mp-TiO ₂）上形成的PbS QD不显示PbSO ₄而是具有PbSO ₃氧化性。通过在mp-TiO ₂ / PbS QD和聚-3-己基噻吩之间引入钙钛矿中间层，PbS QD中的PbSO ₃氧化物质被完全去除，因此与原始相比，PbS QD-SSC的效率提高了90％以上。 PbS QD-SSC。
