Screen-Printed Multiwall Carbon Nanotubes Film as a Counter Electrode for High Efficiency Dye-Sensitized Solar Cells
Multiwall carbon nanotubes (MCNTs) films have been prepared by using single and efficient screen printing method and used as counter electrodes for dye-sensitized solar cells (DSSCs). The asprepared MCNTs counter electrodes exhibit a highly interconnected network structures with high electrical conductivity and good catalytic activity. By the optimization of as-prepared MCNTs film thickness, photovoltaic conversion efficiency of the cell based on MCNTs counter electrode with 1 μm thickness reaches 6.14% at one sun condition (AM 1.5G, 100 mW cm–2), which is comparable to the cell based on conventional Pt counter electrode. These results suggest that the screen- printed MCNTs films provide a potential feasibility for replacing conventional Pt counter electrodes for DSSCs.
