| The alizarin and phenylfluorone metal-free dyes were adsorbed on the surface of TiO2 nanoparticles constituting mesoporous coating of the photoanode, and acted as sensitizers in dye-sensitized solar cells (DSSC). Due to adsorption, the light absorption was extended to 600 nm and light harvesting efficiency exceeded 65 %. The chemical state of the surface of TiO2 nanoparticles was investigated before and after sensitization by X-ray photoemission spectroscopy (XPS) and X-ray absorption spectroscopy (XAS), showing that Ti-Ti bonds dominate and continuous crystalline structure is present up to the surface. The positions of bands measured by Fourier transform infrared spectroscopy (FTIR) was studied in the context of changes linked to the adsorption process. Better photovoltaic parameters for phenylfluorone are consistent with lower internal resistance of the cells determined by electrochemical impedance spectroscopy (EIS). Ageing of the photocells and introduction of a back reflective layer improved their performance. |
