Open-Circuit Voltage (VOC) Enhancement in TiO2-Based DSSCs: Incorporation of ZnO Nanoflowers and Au Nanoparticles por Borbón Rojas, Susana, Lugo Loredo, Shadai, Pourjafari Nokandeh, Dena, Pineda Aguilar, Nayely, Oskam, Gerko, López, Israel

“…Detailed analysis with electrochemical impedance spectroscopy and intensity-modulated photovoltage and photocurrent spectroscopies (IMVS and IMPS) reveal that the main reason for the increase of VOC is related to the shift of the band edges upon coupling TiO2 with ZnO nanoflowers, even though the electron lifetime at the same charge density actually decreases. …”
