Abstract

The optical and photovoltaic properties of multi-walled carbon nanotubes (MWNT) and polyphenylene vinylene (PPV) composite were investigated. The composite was realized by spin-coating the PPV precursor on thin MWNT films and subsequent conversion at high temperature. A drastic reduction of the photoluminescence efficiency was the result of energy transfer and partial hole transfer from PPV chains to MWNTs, together with the scattering and absorption by MWNTs. Photovoltaic devices were fabricated using the composite, employing MWNT as a hole-collecting electrode. Good quantum efficiency was obtained, about twice than the standard indium tin oxide device.
