Influence of ZnO nanocrystals surface modification on structure and photovoltaic properties of MEH-PPV/nc-ZnO nanocomposite films

Abstract

The influence of interface modifires based on perylen imide dyes and naphthyl phosphonic acid on MEH-PPV/nc-ZnO nanocomposite films morphology was stydied. The better phase compatibility between MEH-PPV and nc-ZnO was obtained if (PI1) and (PI2) were used as the IMs. Use of the IMs led to decrease the fluorescence lifetime quenching (τ₁) and to increase the quenching efficiencies (ηq). It was demonstrated that all IMs increase JSC and VOC.
