Liquid charge transporting material
The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of =180 DEG C. In particular in dye-sensitised solar cells, quantum efficiency higher than with prior art solid organic hole- transporters is reported. The melting point of a large quantity of organic charge transporting materials may be adjusted to a desired value by selecting suitable substituents. Accordingly, general advantages of the liquid state may be associated with the properties of organic charge transporting materials.
