NoteThis paper describes the use of one-dimensional 1D poly3,4-ethylenedioxythiophene nanorod n-PEDOT and modified poly3,4-ethylenedioxythiophene:polystyrene sulfonate PEDOT:PSS films as anode buffer layers in polymer photovoltaic cells based on poly3-hexylthiophene:6,6-phenyl-C61-butyric acid methyl ester. We employed high-speed vibrational milling to disperse the n-PEDOTs into an aqueous PSS medium. Raman spectroscopy measurements revealed quinoid-dominated structures for
these aqueous-soluble n-PEDOT:PSS materials. The presence of the 1D n-PEDOTs in the buffer layer improved the photovoltaic performance AM1.5 = 3.10% of the polymer solar cell relative to that of the system prepared using the unmodified PEDOT:PSS AM1.5 = 2.17%. This enhancement was accompanied by an increase in the values of JSC from 5.85 to 7.62 mA/cm2 and the fill factor from 0.58 to 0.64. The conductivity and polarity of the n-PEDOT–modified buffer layer increased upon increasing the
content of n-PEDOT, resulting in increases of the short-circuit current, open-circuit voltage, and power conversion efficiency of the polymer solar cell incorporating the 1D n-PEDOTs.
