A high efficiency CoCr2O4/carbon nanotubes nanocomposite electrocatalyst for dye-sensitised solar cells†
Abstract
A CoCr2O4/carbon nanotubes (CoCr2O4/CNTs) nanocomposite was successfully synthesised by a facile solution route, and used as an electrocatalyst for dye-sensitised solar cells (DSSCs) for the first time, exhibiting a comparable power conversion efficiency of 8.40% to Pt-based DSSCs (η = 8.68%) owing to the superior electrocatalytic activity of the nanocomposite.
