Abstract: The purpose of the present invention is to improve the throughput of a dye adsorption process in which a dye is adsorbed in a porous semiconductor layer on a substrate and to improve dye use efficiency. In a dye adsorption device of the present invention, a dye solution drop-coating unit 12 performs a first process (dye solution drop-coating process) on an unprocessed substrate G carried in the dye adsorption device 10, in which a dye solution is dropped and coated on a porous semiconductor layer on the substrate G. A solvent evaporating/removing unit 14 performs a second process (solvent removing process) in which a solvent is evaporated and removed from the dye solution coated on the semiconductor layer on the substrate G. A rinsing unit 16 performs a third process (rinsing process) in which unnecessary or extra dye attached to the surface of the semiconductor layer n the substrate G is rinsed and removed.

Abstract: [Problem] To significantly reduce processing time of a step of adsorbing dye in a porous semiconductor layer on a substrate surface. [Solution] A flow of a dye solution is formed in a gap between solution guide surface (92L, 92R) of a nozzle (20) and a substrate (G) during the treatment, and a porous semiconductor layer of a treated surface of the substrate is subject to dye adsorption treatment in this flow of the dye solution. Furthermore, impact pressure from slit-like discharge openings (88L, 88R) and pressure of turbulent flow in groove-like uneven sections (92L, 92R) act in the vertical direction in addition to the flow of the dye solution. Thus, aggregation and association of the dye are hardly caused on a surface part of the porous semiconductor layer of the treated surface of the substrate, the dye efficiently penetrates deeply into the porous semiconductor layer, and the dye adsorption into the porous semiconductor layer proceeds at high speed.
