Abstract

Recently, the conjugated polymer – inorganic nanocomposites have been increasingly studied due to the potential applications of these advanced materials in developing optoelectronic devices. In this work nanocomposite materials thin films based on poly [2-methoxy-5-(2’-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and nanocrystalline TiO2 (nc-TiO2) have been fabricated. The photoluminescence (PL) spectra of pure MEH-PPV and nanohybrid films have shown that the excitation at a 470 nm wavelength leads to the strong quenching in photoluminescent intensity due to the compositions of TiO2 component. Current-voltage (I-V) characteristics of multi-layer device with structure of Al//MEH-PPV:nc-TiO2//PEDOT:PSS//ITO//glass were investigated. The obtained results suggest the application of the hybrid MEH-PPV:nc-TiO2 materials in polymeric solar cells.
