Pt-Ni Alloy Nanoparticles as Superior Counter Electrodes for Dye-Sensitized Solar Cells: Experimental and Theoretical Understanding

Pt–Ni alloy nanoparticles are synthesized and used as counter electrodes in dye‐sensitized solar cells (DSSCs) for the first time. A PCE of 9.15% is achieved with the Pt3Ni counter electrode, displaying an evident improvement compared with the conventional pure Pt (8.33%). The cell stability is also...

Description
Summary:Pt–Ni alloy nanoparticles are synthesized and used as counter electrodes in dye‐sensitized solar cells (DSSCs) for the first time. A PCE of 9.15% is achieved with the Pt3Ni counter electrode, displaying an evident improvement compared with the conventional pure Pt (8.33%). The cell stability is also obviously increased with the Pt3Ni counter electrode.
