Synthesis of carbon nanofibers supported NiMoO4 nanoparticles composites used for liquid thin film solar cells counter electrode

In this paper, PVP is used as the linking agent, and the NiMoO 4 nanoparticles-loaded carbon nanofibers composite NiMoO 4 /CNFs is prepared by the hydrothermal process, and it replaced the traditional Pt counter electrode. Obviously, NiMoO 4 nanoparticles are tightly loaded on carbon fibers, which helps to increase the overall catalytic active site. The results of specific characterization tests reveal that NiMoO 4 /CNFs composite has excellent electrocatalytic activity and stability. In the issue, DSSCs using NiMoO 4 /CNFs instead of Pt counter electrode reveal a photovoltaic conversion efficiency (PCE) of 7.67% versus Pt of 7.17% and CNFs of 5.65%, and it is expected to become an efficient alternative material for traditional Pt electrodes .
