Uncovering the charge transfer and recombination mechanism in ZnS-coated PbS quantum dot sensitized solar cells

•The photovoltaic performances of PbS QDSSCs were enhanced by coating ZnS layers.•The charge transfer and recombination mechanism was uncovered in PbS/ZnS QDSSCs.•Electron injection from PbS QDs to TiO2 was studied by transient grating technique.•Suppressed interfacial recombination was observed in...
