NOVELTY - A catalytic layer (102') of counter-electrodes of dye-sensitized solar cells is manufactured by depositing catalyst precursor paste or precursor solution layer (102) over counter-electrodes conductive and transparent substrates (101) by screen-printing, doctor blade, spin-coating, or brush and irradiating catalyst precursor paste or precursor solution layer with continuous wave (CW) or pulsed laser beam (104) having wavelength in range of infrared e.g. carbon dioxide (CO2), neodymium-doped yttrium aluminum garnet (Nd:YAG), or Nd-doped yttrium orthovanadate (Nd:YVO4).    USE - Manufacture of catalytic layer of counter-electrodes of dye-sensitized solar cells (claimed).    ADVANTAGE - Masks over Pt layer when processing titanium(IV) oxide (TiO2) layer are avoided, planarity of glass substrates is maintained, and firing on glass substrates, integrating dye-sensitized solar cell modules with other devices on single substrate, and using flexible plastic substrates are possible.
