Figure 8.

Calculated PCE for NH (a–d) and ND (e–h) arrays as a function of varying geometry parameters (i.e., height, h, diameter, D, array pitch, P and MAPbI${}_3$ thickness, t). Dashed lines show the PCE of flat structures with t = 110 nm or 110$\pm \left|h\right|$ nm, while red triangle lines show the PCE of flat structures with a combined thickness that accounts for the presence of two effective Fabry–Pérot cavities in the nanostructured structure.
