摘要： The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of ≤180°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.
