A process is provided for producing an anode for an electrochemical cell, in particular a solar cell, on electrically conductive glass to which a layer of porous metal oxide is applied. The layer includes metal complexes of the porphyrin-phthalocyanine class and other dyestuffs and is then subjected to a heat treatment. A paste of highly dispersed metal oxide, in particular aluminum oxide and/or titanium oxide, is first produced with the addition of a dyestuff and an alcoholic solution, which acts as a binder, in a dry atmosphere. The paste produced in this way is applied as a thin layer to the glass plate coated with a transparent, electrically conductive layer, and the configuration including the glass plate and the pasty metal oxide layer is subjected to a heat treatment at temperatures below 300.degree. C.
