Abstract
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.
