Abstract EN
Nonstoichiometric nickel oxide ( N i O x ) has been deposited as thin film utilizing indium-doped tin oxide as transparent and electrically conductive substrate.
Spray deposition of a suspension of N i O x nanoparticles in alcoholic medium allowed the preparation of uniform N i O x coatings.
Sintering of the coatings was conducted at temperatures below 500°C for few minutes.
This scalable procedure allowed the attainment of N i O x films with mesoporous morphology and reticulated structure.
The electrochemical characterization showed that N i O x electrodes possess large surface area (about 1000 times larger than their geometrical area).
Due to the openness of the N i O x morphology, the underlying conductive substrate can be contacted by the electrolyte and undergo redox processes within the potential range in which N i O x is electroactive.
This requires careful control of the conditions of polarization in order to prevent the simultaneous occurrence of reduction/oxidation processes in both components of the multilayered electrode.
The combination of the open structure with optical transparency and elevated electroactivity in organic electrolytes motivated us to analyze the potential of the spray-deposited N i O x films as semiconducting cathodes of dye-sensitized solar cells of p-type when erythrosine B was the sensitizer.
