The present invention aims to provide a light-concentrating film capable of concentrating at least one of direct sunlight and diffuse sunlight with high efficiency; a photovoltaic module having the light-concentrating film; and a transfer mold (die) for producing the light-concentrating film. The present invention relates to a light-concentrating film including alternating fine concavo-convex structure on at least one surface, the film having a concavo-convex height (H) of 0.05 to 15 µm and a concavo-convex pitch (P) of 0.05 to 50 µm, the film concentrating at least one of direct sunlight and diffuse sunlight.
本发明旨在提供一种聚光薄膜,能够高效聚光直射太阳光和漫射太阳光中的至少一种;一种具有该聚光薄膜的光伏组件;以及一种用于生产该聚光薄膜的转移模(die)。本发明涉及一种聚光薄膜,包括至少一个表面上的交替精细凹凸结构,该薄膜的凹凸高度(H)为 0.05 至 15 微米,凹凸间距(P)为 0.05 至 50 微米,该薄膜可聚光直射阳光和漫射阳光中的至少一种。
