A Novel nanodiamond/zinc nanocomposite as potential counter electrode for flexible dye sensitized solar cell.

In this study, a novel nanodiamoands (NDs)/zinc (Zn) nanocomposite have been investigated as counter electrode (CE) in flexible dye sensitized solar cell (DSSC) device as potential replacement for platinum (Pt). Simple drop casting method has been employed to fabricate CE on indium tin oxide (ITO) c...
