Organic photovoltaic devices (OPD) using high conductive transparent few-walled carbon nanotubes (FWNT) film prepared by spraying was fabricated as a selective hole collection. Photovoltaic response with different sheet resistance and the transparency of FWNT film was investigated. Maximum efficiency of OPD up to 0.61% with the structure of FWNT (, )/poly(3-hexylthiophene): [6-6]phenyl--butyric acid methyl ester/Al demonstrates a promising alternative of ITO (0.68%) with almost identical operation. The performance improvement results from the optimal balance between sheet resistance and transparency with three-dimensional network interface between nanotubes and polymers.
