Method and apparatus for production of dssc

Abstract

An apparatus and method for producing a dye-sensitized cell are provided, in which a pre-transparent electrode and an opposite electrode are partially bonded, dye molecules are applied to the bonded electrodes followed by washing, an electrolyte is injected, and then the electrodes are hermetically sealed. With the apparatus and method, the manufacturing cost can be reduced and the manufacturing process can be simplified.

1 . A method for producing a dye-sensitized solar cell which includes a transparent electrode, an opposite electrode which is opposite to the transparent electrode, and an electrolyte layer between the two electrodes, the method comprising:
 (a) providing a pre-transparent electrode by coating oxide nanoparticles on a transparent conductive substrate and sintering the resulting transparent conductive substrate;   (b) providing an opposite electrode by coating a transparent conductive substrate with platinum or carbon;   (c) laminating the pre-transparent electrode and the opposite electrode such that the two electrodes are spaced apart by a predetermined interval from each other and the coated oxide nanoparticles and the coated platinum or carbon are positioned between the two electrodes, and then bonding the two electrodes at one or more predetermined portions such that the space between the two electrodes is in fluid communication with the outside;   (d) supplying photosensitive dye molecules to the space between the two electrodes such that the photosensitive dye molecules are adsorbed onto the oxide nanoparticles;   (e) supplying an electrolyte into the space between the two electrodes; and   (f) hermetically sealing the electrodes.   
     
     
         2 . The method according to  claim 1 , wherein in step (c), the bonded portion or portions have at least one first opening therein and at least one second opening therein, through which the space between the two electrodes is in fluid communication with the outside. 
     
     
         3 . The method according to  claim 2 , wherein at least one of the first openings, at least one of the second openings, or both are formed after the bonded portion or portions are formed. 
     
     
         4 . The method according to  claim 1 , wherein step (d) is performed by supplying a solution containing the photosensitive dye molecules. 
     
     
         5 . The method according to  claim 1 , further comprising, prior to step (f), the step of removing remaining dye molecules that have not been adsorbed onto the oxide nanoparticles. 
     
     
         6 . The method according to  claim 5 , wherein the remaining photosensitive dye molecules are removed by supplying a washing solution. 
     
     
         7 . The method according to  claim 6 , wherein the remaining washing solution is removed by supplying air.
