According to one embodiment, a method of forming a solar energy converter assembly disclosed herein includes providing a solar energy converter configured to convert light incident on a light-receiving surface thereof into another form of energy and providing louver elements adjacent to the light-receiving surface such that light is transmittable between the louver elements to the light-receiving surface along a plurality of directions. Display surfaces of the louver elements are visible along a predetermined direction different from the plurality of directions and non-display surfaces of the louver elements reflect light to the light-receiving surface.
