Description
Summary:D- capital pi -A pyridinium dye without carboxylic acid moiety as anchoring group has been used as a photosensitizer for dye-sensitized solar cells (DSSCs). FTIR and absorption spectra of the D- capital pi -A pyridinium dye adsorbed on TiO sub(2) nanoparticles indicate that the dye is adsorbed on the TiO sub(2) surface by an electrostatic interaction between pyridinium moiety of the dye and the hydroxyl group of TiO sub(2) surface. DSSC based on the D- capital pi -A pyridinium dye had a power conversion efficiency ( eta ) of 0.09% with a short-circuit photocurrent density (J sub(sc)) of 0.48mA cm super(-2).
