Abstract
In this study, a transparent NiCo2S4 thin film as an effective counter electrode (CE) was incorporated into a Pt-free dye-sensitized solar cell (DSC) for the first time. NiCo2S4 was synthesized via a facile solvothermal method and then subjected to electrophoresis onto a fluorinated tin oxide (FTO) glass substrate. X-ray diffraction, energy dispersive spectrum, and field-emission scanning electron microscope confirmed that the NiCo2S4 nanoparticles were successfully synthesized and deposited onto the FTO substrate, while the electrochemical analyses showed its superior electrocatalytic activity for the I3â reduction compared to the conventional Pt CE. Additionally, the NiCo2S4 CE demonstrated a high transmittance (>Â 75%) at visible wavelengths. Thus, the DSC assembled with the transparent NiCo2S4 CE achieved a promising photovoltaic conversion efficiency of 6.14% in comparison with that using the Pt CE (6.29%).
