In this study, polymeric nanocomposites of poly(3,4-ethylenedioxythiophene): poly( styrene sulfonate) (PEDOT:PSS) and functionalized multi-walled carbon nanotubes (MWCNTs) were spin coated on a pre-patterned ITO glass and used as a hole conducting layer in organic photovoltaic cells. The multi-layered ITO/MWCNT-PEDOT:PSS/CuPc/C60/Al devices were fabricated to investigate the current density-voltage characteristics and power conversion efficiency. The power conversion efficiency obtained from the device with a concentration of 1.0 wt% MWCNT in the PEDOT: PSS layer was increased twice as those adopted from device without MWCNT doping in the PEDOT: PSS layer and current density-voltage characteristics was also improved well with incorporation of MWCNTs.
