| Abstract: |
We report an inexpensive fabrication route of mesoporous counter electrode, made of chain-like Pt nanoparticles using tubular halloysite clay template. Pre-coated halloysite tube (HT) onto a conducting substrate acts as material synthesising platform for highly interconnected chain-like Pt nanostructure. The Pt-HT composite counter electrode shows effective electrolyte interaction, and high catalytic activity towards tri-iodide reduction. As a result, Pt-HT counter electrode based dye-sensitised solar cells exhibits high energy conversion efficiency of 9.5% than the flat-type Pt film based counter electrode (8.2%) using liquid-type electrolyte. |
