More Information
Summary: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, Jsc (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.
