Summary:The present invention relates to a novel organic dye and to a method for preparing same. A dye compound of the present invention is used in a DSSC (dye-sensitized solar cell) to achieve dramatically improved molar absorptivity, short-circuit photocurrent density (Jsc), and photoelectric conversion efficiency as compared to conventional dyes, and enables refining even without using an expensive column, thus significantly reducing the costs of the synthesis of dyes. La présente invention concerne un nouveau colorant organique et son procédé de préparation. Un composé colorant de la présente invention est utilisé dans une DSSC (cellule solaire sensibilisée au colorant) pour obtenir une absorptivité molaire fortement améliorée, une densité de courant photoélectrique de court-circuit (Jsc) fortement améliorée et une efficacité de conversion photoélectrique fortement améliorée par rapport aux colorants classiques. Le composant permet un raffinage même sans utiliser de colonne onéreuse, réduisant ainsi significativement les coûts de la synthèse des colorants.
