(a) Comparison between the short-circuit currents generated by silicon NCHs with different θ and ϕ and the Yablonovitch limit (Y limit). (b) The 3D-histogram of the short-circuit currents under different ϕ values of silicon NCH with different θ values, which is used for visual clarity and sharp contrast.
