dc.description.abstract | Strong interlayer photoresponses in monolayer (ML) semiconductor stacks, such as substantial light absorption and charge separation across interlayer band alignments, suggest potentials for two-dimensional photovoltaics (PVs). Here, we report an interlayer PV conversion in a type-I ML heterojunction by ultrafast interlayer transfer of photoexcited hot carriers in the broad spectral ranges. Specifically, low-energy photoexcitation on a stack of a narrow-band-gap (Eg) Bi2Te3 few-layer and a large-Eg MoS2 ML permits interlayer transfer of transient hot carriers from the Bi2Te3 layer to the excitonic states of the neighboring MoS2 ML within a time scale of ��70 fs, producing interlayer charge separation. Thereby we achieve substantial conversion efficiency from a MoS2 ML with visible to infrared light illumination. ? 2017 American Chemical Society. | - |
