Organic Sensitizers containing Ullazine chromophore for Dye-Sensitized Solar Cells |
| 초록 |
Many metal-free organic dyes have been used in DSSCs such as coumarin, merocyamine, indoline the molecular structure of the electron donor and the acceptor bridged by the conjugated chain (D-π-A). More and more efforts have been dedicated to development of metal-free organic dyes which exhibit not only higher molar extinction coefficients, but also simple preparation and purification procedures at lower cost. In this article, we have developed novel organic dyes in which the ullazine core was used as the π-bridge and various donor groups were added for the application of DSSCs. An aromatic, 14π-electron annulene resonance structure consisting of a centralized electron density from the inplane nitrogen provides the potential donating strength as well as electron stabilizing properties of this nitrogen-containing heterocycle. The photovoltaic performance of DSSC composed of organic chromophores were measured and evaluated by comparison with that of pristine ruthenium dye. |
