Efficient electron transfer and sensitizer regeneration in stable pi-extended tetrathiafulvalene-sensitized solar cells.

Abstract:

The development of metal-free organic sensitizers is a key issue in dye-sensitized solar cell research. We report successful photovoltaic conversion with a new class of stable tetrathiafulvalene derivatives, showing surprising electrochemical and kinetic properties. With time-resolved spectroscopy we could observe highly efficient regeneration of the photo-oxidized tetrathiafulvalene sensitizers, which were attached to a mesoporous TiO(2) film, by a redox mediator in the pores (iodide/tri-iod...
