摘要
Lead sulfide(PbS) colloidal quantum dots(CQDs), which possess tunable near-infrared absorption,1 multiple exciton generation effect, and solution processability,2 have emerged as attractive candidates for thin film photovoltaic applications.Perovskite solar cells(PSCs) are promising low-cost photovoltaic technologies with high solar-to-electric power conversion efficiency(PCE).The heterojunctioich the hole-accepting material is distributed in the perovskite layer with a gradient.This structure cn structure between perovskite and charge extraction layers is crucial to the photovoltaic performance of PSCs.Here, we report PSCs with a perovskite-PbS quantum dots graded heterojunction(GHJ), in whan enhance the PCE as it improves the photohole collection and reduces recombination loss.By controlling the concentration of PbS colloidal quantum dots and achieved conversion efficiencies up to 8.02%.Absorption of PbS CQDs also extends the absorption spectrum of perovskite solar cells into the infrared region.
