Abstract

Electronic characteristics of organic/inorganic hybrid devices based on CdS nanoparticles, poly(p-phenylene vinylene) (PPV) and poly(sodium styrene sulfonate) (PSS) were investigated. The average diameter of anionic CdS nanoparticles was measured to be 4 nm as judged from TEM and optical spectral characterization. The Quantum efficiency of the ITO/(PPV/PSS)₁₅(PPV/CdS)₅/Al device was significantly improved in comparison with that of the ITO/(PPV/PSS)₂₀/Al device. The performance improvement of the ITO/(PPV/PSS)₁₅(PPV/CdS)₅/Al device is believed to be due to the low energy barrier of CdS nanoparticles for the electron injection from Al electrode.
