Abstract

We report a combined experimental and theoretical study on the origin of the different open circuit potentials observed in dye-sensitized solar cells using Ru(ll)-polypyridyl homoleptic and heteroleptic sensitizers. We have measured the photovoltaic data of different sensitizers and used DFT calculations to analyze the electronic structure of dye-sensitized TiO ₂ nanoparticles. Heteroleptic sensitizers adsorb onto TiO ₂ via a single bipyridine, leading to a TiO ₂ conduction band downshift and overall reduction of the cell open circuit potential.
