[摘要]：We demonstrate a highly efficient hybrid crystalline silicon (c-Si) based photovoltaic devices with hole-transporting transparent conductive poly-(3,4-ethlenedioxythiophene):poly(styrenesufonic acid) (PEDOT:PSS) films, incorporating a Zonyl fluorosurfactant as an additive, compared to non additive devices. The usage of a 0.1% Zonly treated PEDOT: PSS improved the adhesion of precursor solution on hydrophobic c-Si wafer without any oxidation process. The average power conversion efficiency eta value was 10.8%-11.3%, which was superior to those of non-treated devices. Consequently, c-Si/Zonyl-treated PEDOT: PSS heterojunction devices exhibited the highest eta of 11.34%. The Zonyl-treated soluble PEDOT: PSS composite is promising as a hole-transporting transparent conducting layer for c-Si/organic photovoltaic applications. (C) 2012 American Institute of Physics.
