A timepiece includes a dial plate, and a solar battery which is disposed on a rear side of the dial plate. The dial plate is provided with grooves or ridges. The grooves or the ridges have portions where inclination angles with regard to a normal line of the dial plate are different, and due to this, light which is transmitted through the dial plate is incident from a plurality of directions with angles which are different with regard to the solar battery.

Assembly for the display of at least one piece of information for a portable object, this display assembly (1) including a first, at least partially transparent, display device (2) which is located on the side of an observer (4) and arranged to display at least a first piece of information, a second, at least partially transparent, display device (6) for displaying at least a second piece of information and a solar cell (10) being disposed in that order underneath the first display device (2), the first and second display devices (2, 6) being capable of switching between an active state in which they display information and a passive state in which they do not display information.

A power management method for a solar watch or a solar automatic watch. The power management method including at least one providing a primary power supply from at least one energy supplier. The primary power supply is converted to a secondary power supply when the primary power supply reaches at least one primary threshold and/or at least one secondary threshold. A motor is supplied with the secondary power supply such as to wind a mainspring via the motor.

Systems and methods for generating electrical current from at least one photovoltaic cell is described herein. The photovoltaic cell may be disposed over a display of an electronic device. The photovoltaic cell may comprise first and second conductive layers and a photovoltaic layer. The first conductive layer may be etched such that a width of the metal layer is less than a width of the photovoltaic layer providing visibility to the display disposed below. In some embodiments, a capacitive touch sensor is disposed between the metal layer and the absorber layer for providing interaction with a user.
