Abstract

PbS/CuS hetero-nanostructured (HNS) quantum dots(QDs) with finely controlled PbS core-size (˜3, ˜5, and ˜7 nm) and CuS content (4, 7, 11, 14, 17, and 45 mol%) were successfully synthesized via the suppressed cationic exchange reaction rate by reducing the reaction temperature down to −3 °C. By the precise synthesis of the PbS/CuS HNS QDs, we found that the PbS/CuS HNS QDs with ˜3 nm in core-size and 14 mol% CuS have the most effective charge separation/injection from the HNS QDs to the mesoscopic TiO ₂ electron conductor, thereby the sensitized solar cells exhibited high power conversion efficiency of 9.3%.
