NOVEL ORGANIC DYE AND METHOD FOR PREPARING SAME |
摘要 |
<p>The present invention relates to novel organic dye and method for preparing the same. A dye compound of the present invention comprises: a specific aliphatic compound as an electron donor; and a thiopheneic or dehydrothiopheneic unit in an intermediate connecting part (spacer). The dye compound of the present invention is used in a dye-sensitized solar cell (DSSC) to improve a molar extinction coefficient, Jsc (short circuit photocurrent density) and photoelectric conversion efficiency as compared with those of conventional dyes, and thus significantly improves the efficiency of the solar cell. The dye compound of the present invention can be refined without using expensive columns, thereby remarkably reducing costs for dye synthesis.</p> |
