High electrocatalytic activity of self-standing hollow NiCo2S4 single crystalline nanorod arrays towards sulfide redox shuttles in quantum dot-sensitized solar cells.
Self-standing single crystalline NiCo2S4 hollow nanorod arrays are prepared for catalysing the polysulfide redox couple in quantum dot-sensitized solar cells (QDSCs). The QDSCs using NiCo2S4 as a counter electrode (CE) achieved a power conversion efficiency of 4.22%, which exceeds the performance of QDSCs based on a Pt CE by 38.4%.
