This disclosure relates to novel organic dye and a method for preparing the same. The dye compound of the present invention, when used for a dye-sensitized solar cell (DSSC), shows improved molar absorption coefficient, J
sc
(short circuit photocurrent density) and photoelectric transformation efficiency, compared to dyes of the prior art, thus largely improving solar cell efficiency, and it may be purified without expensive column thus remarkably lowering dye synthesis cost.
本公开涉及一种新型有机染料及其制备方法。本发明的染料化合物在用于染料敏化太阳能电池(DSSC)时,与先前技术的染料相比,显示出改进的摩尔吸收系数、Jsc(短路光电流密度)和光电转换效率,从而大大提高了太阳能电池的效率,并且可以在不使用昂贵的柱层析的情况下进行纯化,因此显著降低了染料合成成本。
