Fig. 10 (a 1 –a 4 ) Fabrication process of inverted nanocone AAO, nanocone PDMS, and inverted
nanocone epoxy. Top and angular view SEM images of (b) nanocone PDMS mold and (c) inverted
nanocone epoxy substrate. (d 1 –d 4 ) Fabrication process of perovskite solar cells on the inverted nanocone epoxy. (e 1 –e 4 ) FDTD simulation (Generation rate) of perovskite solar cells fabricated
on planar and inverted nanocone substrates with aspect ratios of 0.25, 0.5, and 1.0. (f) Reflectance
spectra of perovskite films and (g) J-V curves of perovskite solar cells fabricated on inverted nanocone epoxy with aspect ratios of 0 (planar), 0.25, 0.5, and 1.0. The inset image is cross-sectional
