A method of dye adsorption for a photosensitizing dye, the method comprising adsorbing the photosensitizing dye onto an electrode material layer that functions as the working electrode of a dye-sensitized solar cell, within a reaction vessel containing a solution of the photosensitizing dye, wherein a flow of the photosensitizing-dye solution is generated by means of a flow generation part in a direction perpendicular to the electrode material layer and/or a direction parallel thereto, and the flow rate of the photosensitizing-dye solution on the electrode material layer is higher than the diffusion velocity of the photosensitizing dye. La présente invention a trait à un procédé d'adsorption de colorant pour un colorant photosensibilisant qui comprend une étape consistant à adsorber le colorant photosensibilisant sur une couche de matériau d'électrode qui fonctionne en tant qu'électrode de travail d'une cellule solaire à colorant, à l'intérieur d'un récipient de réaction contenant une solution de colorant photosensibilisant, un écoulement de la solution de colorant photosensibilisant étant généré au moyen d'une partie de génération d'écoulement dans une direction perpendiculaire à la couche de matériau d'électrode et/ou dans une direction parallèle à celle-ci, et le débit de la solution de colorant photosensibilisant sur la couche d'électrode étant supérieur à la vitesse de diffusion du colorant photosensibilisant.
