Abstract

L'invention concerne un nouveau colorant organique destiné à un dispositif de conversion photoélectrique à colorant, et son procédé de préparation. Le colorant organique selon l'invention est utilisé en tant que dispositif de conversion photoélectrique à colorant dans une cellule solaire à colorant (DSSC) et présente un pouvoir d'absorption molaire supérieur, un Jsc supérieur (densité de photocourant de court-circuit) et un rendement de conversion photoélectrique supérieur, par rapport à des colorants connus, ce qui permet d'augmenter considérablement le rendement de la pile solaire.
