By combining nanoimprint lithography technique and a two‐step lift‐off process , a Si nanotube array is fabricated and applied as a light absorber for n‐Si/PEDOT:PSS hybrid solar cells. The light is effectively trapped within the nanotubes and the device reveals a J sc of 29.9 mA·cm −2 and a power conversion efficiency of 10.03%, which is an enhancement of 13.4% compared to the cell having the best‐known Si architecture of nanocones as a light absorber to date.
