The increasing demand for power supply as well as environmental concern for the consumption of fossil fuel have triggered global research on the development of clean and renewable energy sources. Due to their low costs, DSSC devices appear to be a good alternative to the siliconbased solar cells. Up to now, intensive researches were performed in order to increase the photoconversion efficiency. Typical DSSCs consist of a dyed semiconductor TiO2 photoelectrode, a Pt counter electrode and redox electrolyte. Photosensitizer played a crucial role in these devices and it is fundamental to the cell’s performance and stability. It absorb visible light and inject electrons into the conduction band of the TiO2 after solar light excitation and thus generate the photocurrent via redox mediator in electrolytes.

Abstract
The increasing demand for power supply as well as environmental concern for the consumption of fossil fuel have triggered global research on the development of clean and renewable energy sources. Due to their low costs, DSSC devices appear to be a good alternative to the siliconbased solar cells. Up to now, intensive researches were performed in order to increase the photoconversion efficiency. Typical DSSCs consist of a dyed semiconductor TiO2 photoelectrode, a Pt counter electrode and redox electrolyte. Photosensitizer played a crucial role in these devices and it is fundamental to the cell’s performance and stability. It absorb visible light and inject electrons into the conduction band of the TiO2 after solar light excitation and thus generate the photocurrent via redox mediator in electrolytes. In this presentation it will be reported the contribution of the “Fundamentals of Chemical Technologies” group in Lecce to the development of high performing materials for Dye Sensitized Solar Cells.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
