Abstract

Use of TiOF2 as semiconductor in a photoelectric conversion device, in particular in a dye-sensitized solar cell. A photoelectric conversion device, in particular a dye-sensitized solar cell, comprising a semiconductor layer containing at least TiOF2. The TiOF2 is preferably used in the form of nanoparticles. Dyes, method(s) of making them, and their use in photoelectric conversion devices, especially in dye-sensitized solar cells. A dye-sensitized solar cell comprising at least one fluorinated compound as a dye and at least TiOF2 as semiconductor.
