More Information
Summary:The present invention relates to a novel organic dye and a method for preparing same. The dye compound of the present invention is used in a dye-sensitized solar cell (DSSC), and improves molar absorptivity, short circuit photocurrent density (Jsc) and photoelectric converting efficiency which significantly enhances the efficiency of the solar cell. The novel organic dye and preparation method therefor according to the present invention allows for refining the process without requiring an expensive column and remarkably reduces costs for dye synthesis. L'invention concerne un nouveau colorant organique et son procédé de préparation. Le composé colorant de l'invention est utilisé dans une cellule solaire sensible à un colorant (DSSC), et permet d'améliorer le coefficient d'absorption molaire, la densité du photocourant de court-circuit (Jsc) et le rendement de conversion photoélectrique, ce qui améliore de manière significative le rendement de la cellule solaire. Selon l'invention, le nouveau colorant organique et son procédé de préparation permettent d'affiner le procédé à exécuter sans avoir recours à une colonne chère et de réduire de manière remarquable les coûts de synthèse du colorant.
