Novel D-π-A Structured Zn(II)-porphyrin Sensitizers for Highly Efficient Dye-sensitized Solar Cells |
| 초록 |
Dye-sensitised solar cells (DSSCs) have been widely regarded as next-generation photovoltaics for providing electricity at lower expense and with more versatility. Porphyrins are one of the most widely studied sensitisers for DSSCs because of their strongly absorbing Soret bands (400-450 nm) and moderately absorbing Q-bands (550-600 nm). In fact, the push–pull porphyrin sensitizer (SM315) with co-adsorbent (CDCA) using a cobalt-based electrolyte attained a power conversion efficiency of 13.1%. In this presentation, the design and synthesis of two new push–pull structured (D–π–A) Zn(II)–porphyrin sensitizers based on the structural modification of SM315 containing bulky alkoxy group substituted diphenyl amine and fluorene-derived electron donor moieties for efficient retardation of charge recombination will be described. |
