Title (EN) SOLAR CELL AND METHOD FOR MANUFACTURING SAME
(FR) CELLULE SOLAIRE ET SON PROCÉDÉ DE FABRICATION
(KO) 태양전지 및 그 제조 방법
Abstract:
(EN) The present invention relates to a solar cell wherein some of unit layers constituting the solar cell are simultaneously formed such that light transmittance is improved and a current leak is suppressed, through a tunnel junction technology, thereby enabling the solar cell to have excellent temperature characteristics and photoelectric conversion efficiency or materials of the unit layers constituting the solar cell are designed such that photoelectric conversion efficiency is maximized through current matching between solar cells.
(FR) La présente invention concerne une cellule solaire dans laquelle certaines des couches unitaires constituant la cellule solaire sont formées simultanément de manière à améliorer le facteur de transmission lumineuse et à supprimer une fuite de courant, au moyen d'une technologie de jonction tunnel, ce qui permet à la cellule solaire de présenter d'excellentes caractéristiques de température et un excellent rendement de conversion photoélectrique, ou des matériaux des couches unitaires constituant la cellule solaire sont conçus de manière à maximiser le rendement de conversion photoélectrique par adaptation de courant entre cellules solaires.
(KO) 본 발명은 태양전지를 구성하는 단위 층들의 일부를 동시에 형성함으로써 터널 접합 기술에 의해 광투과도를 향상시키고 누설전류를 억제하며 우수한 온도 특성 및 광전 변환 효율을 가지거나 또는 태양전지를 구성하는 단위 층들의 재료를 설계하여 각 태양전지들 사이의 전류 매칭을 통해 광전 변환 효율을 극대화 한 태양전지에 관한 것이다.
