Abstract
Electrode comprising a conductive substrate on which a uniform layer of aggregates A, having an average diameter ranging from 40 to 100 nm, is deposited, on which a non-homogeneous distribution of aggregates B, having an average diameter ranging from 300 nm to 1,200 nm, is superimposed, both of said aggregates being composed of particles containing one or more metals Me selected from platinum, palladium and gold, having an average diameter ranging from 8 to 10 nm. The use of said electrode, as cathode, for DSSC devices produces a marked improvement in the performances of the cell with respect to the results that can be obtained with known cathodes.
