Abstract
We propose a simple fabrication method of thin film hybrid solar cells by combining single‐walled carbon nanotubes (SWCNTs) and poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) with hydrogenated amorphous silicon (a‐Si:H). Electrically conductive polymer PEDOT:PSS introduced in a randomly oriented network of SWCNTs forms a coupled continuous heterojunction between PEDOT:PSS–SWCNT and a‐Si:H. We fabricated and compared the performance of SWCNT/a‐Si:H, PEDOT:PSS/a‐Si:H and PEDOT:PSS–SWCNT/a‐Si:H solar cells. The PEDOT:PSS–SWCNT/a‐Si:H solar cells resulted to have an efficiency of 1.6% with state‐of‐the‐art fill factor and open circuit voltage of 54% and 0.803 V, respectively.
