Abstract

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.
