It is found that efficient charge separation occurs at the interfaces of MEH-PPV/ TiO2 nanorods, accompanying with a significant quench in the photoluminescence (PL) intensity and a decrease of PL lifetime with increasing TiO2 nanorod concentrations. The device based on the MEH-PPV/ TiO2 nanorod hybrid material shows power efficiency about 2.2% at the incident light with a wavelength of 565 nm. The transport properties of the solar cells are further investigated and discussed.[SDGs]SDG7Electron transport properties; Organic polymers; Photoluminescence; Photovoltaic cells; Quenching; Titanium dioxide; Charge separation; Nanorod concentrations; Nanorods; Power efficiency; Nanostructured materialsconference paper10.1117/12.6787832-s2.0-33846231845
