PROBLEM TO BE SOLVED: To provide a blind with a solar battery making the most of the advantages of a blind where a solar battery is fixed (good design quality and capability for controlling the amount of light shining in) and having high generation efficiency.SOLUTION: A slat 10 of the blind comprises: a condenser 1; a power generation part 2 having a solar battery; and a micro prism sheet 6. The section of the condenser is triangular, and a solar battery is disposed on the position of the base 1c. Light coming through a surface 1a, one of two surfaces forming the vertical angle, reflects on the opposite surface (the reflection surface 1b), and enters the solar battery. The light that is refracted on the reflection surface 1b and passes through the condenser 1 is greatly refracted by the micro prism sheet 6 and guided into a room. |
