Supramolecular Co-adsorption on TiO2 to enhance the efficiency of dye-sensitized solar cells

Three single dyes show poor PCEs respectively, and the PCEs are greatly improved by mutual co-sensitization. It is found that two different dyes of co-sensitization have supramolecular action when adsorb on the surface of TiO₂. This work reveals a new discovery to offer a great promise for improving the photovoltaic performance through supramolecular action.
