Abstract: front page image
(EN)Disclosed is a method for manufacturing a counter electrode which comprises the steps of: adding graphene to a dispersion liquid to make a graphene-mixed solution; inserting a transparent electrode into the mixed solution and applying a voltage for 5 seconds to 5 minutes to deposit graphene; and heat-treating the graphene at 350°C to 600°C in an N2 atmosphere. The counter electrode using the graphene according to the present invention can be easily manufactured at a low cost and can enable a wide reaction area thereof to be uniformly coated. Accordingly, the counter electrode can be used instead of platinum in a battery cell, and a dye-sensitized solar cell having the counter electrode of the present invention has good current density and efficiency.
(FR)L'invention porte sur un procédé de fabrication d'une électrode auxiliaire qui comporte les étapes suivantes : ajouter du graphène à un liquide de dispersion pour obtenir une solution mélangée de graphène ; introduire une électrode transparente dans la solution mélangée et l'application d'une tension pendant 5 secondes à 5 minutes pour déposer du graphène ; traiter thermiquement le graphène à une température allant de 350°C à 600°C dans une atmosphère de N2. L'électrode auxiliaire utilisant le graphène selon la présente invention peut être facilement fabriquée à bas coût et peut permettre à une large surface de réaction de celle-ci d'être revêtue de manière uniforme. Par conséquent, l'électrode auxiliaire peut être utilisée à la place du platine dans un élément de batterie, et une cellule solaire à colorant ayant l'électrode auxiliaire selon la présente invention présente une bonne densité de courant et une bonne efficacité.
(KO)본 발명은 그래핀을 분산액에 가하여 그래핀 혼합용액을 형성하는 단계; 상기 혼합용액에 투명전극을 투입하고 5초 내지 5분 동안 전압을 가하여 그래핀을 증착시키는 단계; 및 상기 그래핀을 질소 분위기에서 350 내지 600℃로 열처리하는 단계를 포함하는 상대전극의 제조방법을 개시한다. 본 발명에 따른 그래핀을 이용한 상대전극은 제조공정이 용이하고 저렴할 뿐만 아니라, 그래핀의 기본적인 특성으로 인하여 반응면적이 넓고 대면적에 균일하게 코팅하는 것이 가능하다. 그러므로 백금을 대체하여 전지에 사용될 수 있으며, 본 발명의 상대전극을 포함한 염료감응형 태양전지는 전류밀도 및 효율 등이 우수하다.
