ANATASE MULTI-CHANNEL POROUS COATING FILM

摘要

The present invention relates to an anatase multi-channel porous coating film, and more particularly, to an anatase multi-channel porous coating film comprising a plurality of first pores and a plurality of second porous bodies positioned in the first pores. The anatase multi-channel porous coating film of the present invention can easily form multi-channels by forming the second porous bodies in the pores of first porous bodies, and as a result, a contact area of the anatase per unit volume becomes larger than a conventional contact area, so that when used as an electrode of a dye-sensitized solar cell, the anatase multi-channel porous coating film can have a high current density to enhance the energy efficiency of the dye-sensitized solar cell.
