Power generation dynamics for few-layered WSe2 solar cell. (a,b) Typical (a) photocurrent mapping and (b) photocurrent line scan of few-layered WSe2 with an asymmetric electrode (Ti-Ni). (c) Schematic illustration of the photovoltaic power generation dynamics. (d,e) (d) EQE and (e) ΔR/R as a function of the incident photon energy. (f) Ld as a function of the incident photon energy. (g,h) EQE as a function of L ele for different incident photon energies, (f) 1.65, 2.1 eV and (g) 3.1 eV. (i,j) (i) Schematic illustration of band structure of three-layered WSe2 (traced from ref.37) and (j) the exciton transition model for A,B (left), and C (right) excitons.
