Simple and Fast Microwave-Assisted Synthesis Methods of Nanocrystalline TiO₂ and rGO Materials for Low-Cost Metal-Free DSSC Applications.

ABSTRACT: Nanocrystalline TiO₂ and reduced graphene oxide (rGO) materials have been synthesized by a simple and low-cost microwave-assisted hydrothermal method and applied in dye-sensitized solar cells (DSSCs) as photoactive and metal-free counter electrodes, respectively. Different TiO₂ nanocrystalline materials have been synthesized via the acid hydrolysis sol-gel method, followed by microwave hydrothermal treatment at 210 °C and 300 psi and at different microwave irradiation times (20, 30, 45, and 60 min) instead of the usual hydrothermal time of 12 h. The properties of the produced mesoporous nanocrystalline TiO₂ are investigated in terms of their morphology, crystal structure, optical properties, and surface area behavior using relevant characterization techniqu
