Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201305394-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>By combining nanoimprint lithography technique and a two‐step lift‐off process</bold>, 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 <italic>J</italic>_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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghgb1803g" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
