Facile Process for Fabrication of Nanopatterned Counter Electrodes for Dye-Sensitized Solar Cells |
| 초록 |
In this study, Poly(dimethyl siloxane) (PDMS) nanostamps and commercial TiO2 paste were used to fabricate large-area platinum (Pt) counter electrode platforms with mesh-shaped nanopattern simply. Mesh-shaped nanopatterned Pt counter electrodes were easily made by placing patterned PDMS stamps on a TiO2 scaffold followed by Pt-sputtering. These mesh-shaped nanopatterned Pt counter electrodes have advantage in enhanced light harvesting based on a light trapping technique. The efficiency of a ssDSSC with a mesh-shaped Pt counter electrode was 7.0 % which is much higher than that of thermally deposited electrodes with non-patterned (5.4 %) or sputtering deposited electrodes with non-patterned (5.7 %). Our facile process to fabricate Pt counter electrodes is compatible with mass production and can be extended to other metal nanoparticles than Pt. |
