RuO2@Template-Free N-enriched Nano-sphere Carbons from Poly(butyl acrylate)-b-Polyacrylonitrile Block Copolymer as Counter Electrodes for High-Performance Dye-Sensitized Solar Cells. |
| 초록 |
N-enriched nano-sphere carbon containing RuO2 were synthesized by a simple template-free method. Poly(butyl acrylate)-b-Polyacrylonitrile (PBA-b-PAN) copolymer prepared by atom transferred radical polymerization (ATRP), were dissolved in dimethyl sulfoxide (DMF) with ruthenium(III) acetylacetonate, an organic ruthenium precursor, and then pyrolyzed followed by electrospinning. As prepared RuO2@template-free N-enriched nano-sphere carbon (RuO2@TNC) containing mesopore/micropore shows very high efficiency as counter electrode in Co(bpy)32+/3+ (bpy = 2,2′-bipyridine) based dye-sensitized solar cells (DSSC). This greater performance is attributed to self-doped graphitic nitrogen and RuO2 on the pore edge facilitated by high surface area. |
