Solar cells are integrated into a portable device. Multiple cells are arranged on the surface of the device such that a number of solar cells may always be functional and produce a desired voltage even if the rest is obstructed. Information regarding solar cells' functions or performances can be displayed either on the device's main display or on top of the solar cells. Solar cells are typically stacked with other layers made of transparent or semi-transparent materials. These layers are glued with shock absorbent materials. Some of these layers may be used for display or input purposes, and some layers may be coated with various materials or they may be etched with product logos or other patterns. This stack of layers may be attached to the device's frame through a shock absorber.
