ANTIREFLECTION FILM, SOLAR BATTERY CELL, METHOD FOR MANUFACTURING ANTIREFLECTION FILM, AND METHOD FOR MANUFACTURING SOLAR BATTERY CELL

摘要

PROBLEM TO BE SOLVED: To provide a multilayer antireflection film achieving low reflectance over a wide band and a wide incident angle range.

SOLUTION: An antireflection film 10 is composed of a plurality of dielectric layers (11, 12) laminated on the light receiving surface of a photoelectric conversion element 30. In at least one layer of the plurality of dielectric layers, microstructures (columnar bodies 15) are formed over a region which light enters, wherein a width in the longitudinal direction of each microstructure is equal to or less than the maximum wavelength of the light converted into electricity by the photoelectric conversion element.
