A solar cell device includes a solar cell section configured to output a first voltage upon receiving light. A charge pump circuit includes a first charge pump. The first charge pump includes a first terminal and a second terminal. The first terminal is configured to receive the first voltage from the solar cell section, and the second terminal is configured to output a second voltage that is higher than the first voltage. An output section is configured to receive an output voltage output by the charge pump circuit. The charge pump circuit is formed on a single semiconductor substrate.
