title: Relationships between cell parameters of dye-sensitized solar cells and dye-adsorption parameters.
abstract: The performance of dye-sensitized solar cells (DSCs) is affected strongly by sensitizer-dye adsorption behavior on TiO(2) nanocrystal electrode. This study reports quantitative relationships between DSC cell performance parameters and dye-adsorption parameters for the first time. We discovered a logarithmic relationship between short-circuit photocurrent density (J(sc)) and dye-adsorption equilibrium constant on TiO(2) surface, and a linear relationship between open-circuit potential (V(oc)) and dye-adsorption density on TiO(2) surface for DSCs. These relationships provide a convenient method for forecasting the performance of TiO(2) nanoparticles for DSCs from the dye-adsorption parameters, and also indicate future directions for the development of high-performance TiO(2) nanoparticles for DSCs.
