Patent ID: 8316792

Claim:
An apparatus for making a working electrode of a dye-sensitized solar cell, the working electrode comprising a substrate, a titanium dioxide layer formed on the substrate and a photosensitive dye layer formed on the titanium dioxide layer, the apparatus comprising: a columnar body, the columnar body being opened at one end thereof and having a working space defined therein, the columnar body having an accommodating groove formed in an inner wall of the working space, the accommodating groove configured for accommodating a substrate; a rotatable mechanism rotatably received in the working space, the rotatable mechanism comprising a first containing chamber, a second containing chamber coaxially arranged with the first containing chamber, a plurality of first nozzles in communication with the first containing chamber and a plurality of second nozzles in communication with the second containing chamber, the first containing chamber configured for containing one of a titanium dioxide slurry and a photosensitive dye slurry, the second containing chamber configured for containing the other of the titanium dioxide slurry and the photosensitive dye slurry, the first nozzles configured for jetting the one of the titanium dioxide slurry and the photosensitive dye slurry from the first containing chamber to the substrate, the second nozzles configured for jetting the other of the titanium dioxide slurry and the photosensitive dye slurry from the second containing chamber to the working space; and a cover enclosing the columnar body, the cover having a first feeding tube and a second feeding tube extending therethrough, the first feeding tube in communication with the first containing chamber and configured for feeding the one of the titanium dioxide slurry and the photosensitive dye slurry to the first containing chamber, the second feeding tube in communication with the second containing chamber and configured for feeding the other of the titanium dioxide slurry and the photosensitive dye slurry to the second containing chamber.
