  • Solar cell phone
    Patent number: 9680189
    Abstract: A solar cell phone includes a housing having a keypad, a display screen, other electronic components and a rechargeable battery. A diode switch within the housing is electrically connected to the rechargeable battery. A plurality of solar panels are mounted to the housing and electrically connected to the diode switch. The diode switch will allow the solar panels to supply electrical power to the rechargeable battery. An auxiliary battery within the housing receives electrical power from the solar panels. The auxiliary battery will store the electrical power to recharge the rechargeable battery when the diode switch is in a non-operative position, so that the rechargeable battery will continue to operate the keypad, the display screen and the other electronic components within the housing.
