Comparing the optical absorbance of MoS2, MoSe2, and WS2 monolayers with that of graphene shows that TMD monolayers absorb much more sunlight than graphene. The calculated flux of absorbed photons was 4.6, 3.9, 2.3, and 2.0 mA cm−2 for monolayer MoSe2, MoS2, WS2, and graphene, respectively, compared with 0.3 mA cm−2 for GaAs and 0.1 mA cm−2 for Si in the form of 1 nm thin films. A monolayer TMD can absorb as much sunlight as a 50 nm thick Si film. Wang et al. summarized the bandgaps of different atomic layered 2D nanomaterials, including MoS2, MoSe2, MoTe2, WS2, WSe2, ReS2, ReSe2, SnS2, SnSe2, HfS2, HfSe2, ZrS2, ZrSe2, In2Se3, black AsP, black phosphorus (BP), and h-BN with their corresponding photodetection range, varying from near ultraviolet (NUV) to long infrared (LIR). MoS2, WSe2, SnS2, and black phosphorus show a broadband spectral range from NUV to mid-infrared (MIR) wavelength. The optical absorbance of MoS2 thin films can be further extended by developing diverse hybrid heterostructures.
