Dual Functioned Coadsorbents for Highly Efficient Dye-sensitized Solar Cells |
| 초록 |
The triaryl amine-based coadsorbents were developed to use as an alternative to deoxycholic acid (DCA) in organic dye-sensitized solar cells (DSSCs). They have dual functioned properties, that is, the prevention of the л-л stacking of organic dye molecules like a DCA and the light harvesting effect. As a result, The short-circuit photocurrent density (Jsc) by 12 %, open-circuit photovoltage (Voc) by 14 % and overall efficiency by 35 % was increased than NKX2677 based solar cell. The highest photovoltaic performance of η= 8.53 % ever reported for DSSCs employing the coumarin dyes was achieved. The synthesis and characterization of dual functioned coadsorbents based on hole conductors for highly efficient dye-sensitized solar cells will be described. |
