Abstract
The invention relates to the field of dye-sensitized solar cells and discloses a method for reducing the temperature necessary for sintering the metal oxide paste coating the electrode. The method comprises applying a colloid comprising a metal oxide, a solvent and a binder to an electrode and heating the coated electrode to a temperature of at most 300° C. for sintering the metal oxide following by cooling the electrode coated with sintered metal oxide. A process for preparing dye sensitized solar cells is also disclosed.
