Periodic nanocone–nanopillar dual‐structured arrays are wet chemical etched on 20 μm‐thick crystalline silicon substrates, enabling the realization of excellent light absorption properties and enhanced electrical contact with PEDOT:PSS. The finally textured silicon/PEDOT:PSS thin film hybrid solar cell shows a power conversion efficiency of 12.2%. These results provide a viable route toward high‐performance thin film silicon/polymer hybrid cells by shape‐controlled nanotexturing.
