Abstract
The present invention provides an organic dye, a process for producing the same and the use thereof. The organic dye has the structure of formula (I) or formula (II). The regulation of the molecular energy levels and three-dimensional structures are achieved by ring-merging phenanthrocarbazole and an electron-rich thiophene unit as well as by selecting appropriate substituents. Thereby, when the organic dye of the present invention is applied to a dye-sensitized solar cell, the power conversion efficiency of the dye-sensitized solar cell is greatly improved. Meanwhile, the raw materials for the process according to the present invention have plenty of sources with low costs, so that a commercial production can be effected.
