Fig. 5 Characterization of the bioinspired patterned thin PV absorbers. Characterization of the bioinspired patterned thin PV absorbers. (A) 3D AFM image of the bioinspired a-Si:H thin film. 2D surface profile shows a short-range ordered hole distribution that is used for bioinspired solar cell simulation (fig. S7). 1D line profile shows uniform surface patterning with height (etching) profile. (B) Impact of the etched disordered nanoholes on the absorption spectrum measured at normal AOI with unpolarized light. (C) Angular dependence of the IA of the patterned and unpatterned samples. The relative increase in IA raises up to +200% for an AOI of 50°. Radwanul H. Siddique et al.
