Abstract: A window blind is disclosed. The window blind includes a slat having a convex curved surface. The window blind also includes a solar cell module having solar cells and being attached to the convex curved surface of the slat. The carrier generating portions of the solar cells are made of a thin film group III-V compound semiconductor that can be bent, so that the solar cells can be attached to the convex curved surface. The length of the curved surface of the solar cell module in the longitudinal direction is at least half the length of the curved surface of the slat in the longitudinal direction. The solar cell module is disposed eccentrically to one side with respect to the transverse centerline of the slat.
