Dye-sensitised photovoltaic cells, method for the production of said photovoltaic cells and use thereof

摘要

The invention relates to photovoltaic cells which have an additional catalytic intermediate layer between the photoelectrode and the counter electrode, and which contain an electrolyte which comprises at least one ionic liquid and a mixture which is capable of forming a redox-system. The inventive photovoltaic cells, when subjected to high intensive radiation of between 100 1000 watt/m<2>, demonstrate visibly higher efficiency in comparison with known cells without the need for an additional catalytic intermediate layer.
