Abstract:
1. A dye adsorption apparatus of adsorbing a dye into a porous semiconductor layer formed on a treated surface of a substrate, the apparatus comprising: a boat configured to detachably hold a plurality of substrates which are arranged in a row such that the treated surfaces of the substrates face horizontally; a processing tank configured to accommodate the boat and the plurality of substrates held in the boat to be capable of going in and out of the processing tank through a top opening; a top cover configured to close the top opening of the processing tank; a first transport unit configured to transport the boat into and out of the processing tank; a dye solution supply unit configured to supply a dye solution formed by solving the dye in a solvent into the processing tank to such an extent that the plurality of substrates held in the boat are sunk in the dye solution within the processing tank; and a flow control unit configured to control a flow of the dye solution within the processing tank during a dye adsorption processing.
