Abstract:
(EN) A solar cell system that generates power by absorbing sunlight, wherein the solar cell system is provided with a laminated structure and a power-generating cell positioned at the periphery of the laminated structure. The laminated structure is formed by laminating a transparent sheet-shaped member including a wavelength conversion material, and a first transparent sheet. The maximum emission wavelength of the wavelength conversion material is at least 780 nm, and the refractive index na1 of the first transparent sheet is higher than the refractive index nb of the transparent sheet-shaped member. The present invention makes it possible to provide a solar cell system provided with a power-generating cell and a transparent layer capable of effectively guiding light to a side surface, said light entering from the transparent layer surface and being converted internally to light of a high wavelength such as near infrared light.
(FR) L'invention concerne un système de cellule solaire qui génère de l'énergie en absorbant de la lumière solaire, le système de cellule solaire étant doté d'une structure stratifiée et d'une cellule de production d'énergie, positionnée à la périphérie de la structure stratifiée. La structure stratifiée est formée par stratification d'un élément transparent en forme de feuille, contenant un matériau de conversion de longueur d'onde, et d'une première feuille transparente. La longueur d'onde d'émission maximale du matériau de conversion de longueur d'onde est d'au moins 780 nm, et l'indice de réfraction na1 de la première feuille transparente est supérieur à l'indice de réfraction nb de l'élément transparent en forme de feuille. La présente invention permet de fournir un système de cellule solaire doté d'une cellule de production d'énergie et d'une couche transparente, capable de guider efficacement la lumière vers une surface latérale, ladite lumière entrant à partir de la surface de couche transparente et étant convertie à l'intérieur en une lumière à longueur d'onde élevée, telle qu'une lumière proche de l'infrarouge.
(JA) 太陽光を吸収することで発電する太陽電池システムであって、前記太陽電池システムは、積層構造体と前記積層構造体の周辺部に配置された発電用セルを備え、前記積層構造体は、波長変換材料を含有する透明シート状部材と、第1の透明シートとが積層されており、前記波長変換材料の最大発光波長が780nm以上であり、前記第1の透明シートの屈折率na1が前記透明シート状部材の屈折率nよりも高い、太陽電池システムである。本発明によれば、透明層表面から入射され、内部において、近赤外線などの高波長の光に変換された光を、側面に効率よく導くことが可能な透明層及び発電用セルを備える太陽電池システムを提供することができる。
