Abstract: An electronic apparatus includes a solar power module for generating power and inputting information, a power management module for extracting and storing power from the solar power module, a detection unit for detect an electrical parameter variation of the solar power module and generating a detection signal corresponding to the electrical parameter, and an information processing unit for receiving the detection signal from the detection unit and executing a command corresponding to the detection signal. The solar power module has multiple solar power generation units for generating power and inputting information, and the solar power generation unit has multiple solar power generation subunits. The electrical parameter variation is generated from the solar power generation subunit when light absorbed by the solar power generation unit changes.

Abstract: A solar power module includes a solar power generation layer, a first electrode layer, and a second electrode layer. The solar power generation receives photons and includes a number of solar power generation units. The first electrode layer is connected with the solar power generation layer. The second electrode layer is connected with the solar power generation layer, and includes a number of conductive electrodes. Each conductive electrode is connected with one of the solar power generation unit. The conductive electrode transmits an electrical parameter variation of the corresponding solar power generation unit to a detection unit to transform the electrical parameter variation into corresponding input command.

Abstract: An information input module for an electronic device includes a substrate, a first electrode made up of transparent conductive materials, a second electrode, and a solar cell layer disposed between the first and second electrodes. The solar cell layer includes a plurality of solar cells electrically insulated from each other. The plurality of solar cells generates electrical signals in response to a user's operations to activate functions of the electronic device. The first electrode is disposed between the substrate and the solar cell layer. Both the first and second electrodes are electrically connected to each of the plurality of solar cells for transmitting the electrical signals to the electronic device. The electrical signals reflect changes of electrical parameters of one or more solar cells of the plurality of solar cells when light beams are blocked from reaching on, wholly or partially, the one or more solar cells.
