Title (EN) CONDUCTIVE PASTE FOR SOLAR CELL ELECTRODE AND SOLAR CELL MANUFACTURED USING SAME
(FR) PÂTE CONDUCTRICE POUR ÉLECTRODE DE CELLULE SOLAIRE, ET CELLULE SOLAIRE FABRIQUÉE À L'AIDE DE CETTE DERNIÈRE
(KO) 태양전지 전극용 도전성 페이스트 및 이를 사용하여 제조된 태양전지
Abstract: front page image
(EN) The present invention relates to a conductive paste for a solar cell electrode comprising a metal powder, a glass frit, an organic binder, and a solvent. By mixing at least two or more kinds of solvents including a first solvent and a second solvent as the solvent to adjust a surface tension and a boiling point of the solvent, it is possible to enhance conductivity by improving an aspect ratio, i.e., a line width and line pitch, of an electrode which is formed using the conductive paste according to the present invention. In addition, as the line width of the electrode decreases, a light receiving surface increases to provide a solar cell having high generation efficiency.
(FR) La présente invention concerne une pâte conductrice pour une électrode de cellule solaire comprenant une poudre métallique, une fritte de verre, un liant organique et un solvant. Par un mélange d'au moins deux types de solvants, ou plus, comprenant un premier solvant et un second solvant en tant que solvant servant à ajuster une tension de surface et un point d'ébullition du solvant, il est possible d'améliorer la conductivité par une amélioration d'un facteur de forme, c'est-à-dire une largeur de ligne et un pas de lignes, d'une électrode qui est formée à l'aide de la pâte conductrice selon la présente invention. De plus, à mesure que la largeur de ligne de l'électrode diminue, une surface de réception de lumière augmente, ce qui fournit une cellule solaire ayant un haut rendement de génération.
(KO) 본 발명은 금속 분말, 유리 프릿, 유기 바인더 및 용매를 포함하는 태양전지 전극용 도전성 페이스트로서, 용매로서 제1 용매 및 제2 용매를 포함하는 적어도 2종 이상의 용매를 혼합하여 용매의 표면장력 및 비점을 조절함으로써, 본 발명에 따른 도전성 페이스트를 이용하여 형성되는 전극의 종횡비(aspect ratio), 즉 선폭 및 선고를 개선하여 전도성을 향상시킬 수 있으며, 전극의 선폭이 감소에 따라 수광면이 늘어나 높은 발전 효율을 갖는 태양전지를 제공할 수 있다.
