AI Article Synopsis

  • The study examines the electrochemical properties of single-walled carbon nanohorns (SWCNHs) and their oxidized version (ox-SWCNHs) when spray-coated onto fluorine doped SnO2 (FTO).
  • The aim is to evaluate their use in cobalt-based transparent dye-sensitized solar cells (DSSCs) along with a specific redox mediator (Co(bpy)3(2+/3+)).
  • The results show that these nanocarbon materials offer excellent electrocatalytic performance, are easy to produce, and exhibit good stability, making them promising alternatives to traditional noble metal and conductive polymer materials for counter electrodes in advanced photoelectrochemical devices.

Article Abstract

The electrochemical properties of both pristine single walled carbon nanohorns (SWCNHS) and their chemically oxidized form (ox-SWCNHS) spray coated onto fluorine doped SnO2 (FTO) were investigated in the framework of the fabrication of cobalt based transparent dye sensitized solar cells (DSSCs). These new nanocarbon substrates, evaluated in conjunction with the Co(bpy)3(2+/3+) (bpy = 2,2'-bipyridine) redox mediator, are endowed with excellent electrocatalytic properties, ease of fabrication, and very promising stability and display a great potential for replacing the best noble metal and conductive polymer catalytic materials in the building of semitransparent counter electrodes in new generation photoelectrochemical devices.
