NOVELTY - This invention relates to a light and thermal electricity generation device using solar power, which includes at least one light and thermal electricity generation module, the light and thermal electricity generation module consists of a temperature damper and a plurality of solar chips. The temperature damper has at least one electromotive generation end chip and an electronic generation end chip. The non-electrode end surfaces of each electromotive generation end chip and each electronic generation end chip are equipped with a heat absorption panel in mutually-connected manner, and the electrode ends are respectively equipped with a soldering surface and connected with conduction wires and each is equipped with a room-temperature sensing piece. The surface of the heat absorption panel is processed with an insulation treatment and equipped with an electric conduction circuit. The solar chips are arranged and mounted on the heat absorption panel of the temperature damper and are mutually connected through the electric conduction circuit, and are electrically connected with conduction wire on the electrode end of the temperature damper, so that the thermal energy will be absorbed by the heat absorption panel when the solar chip convert the light energy into electric energy, and when the temperature of heat absorption panel of the temperature damper is higher than the temperature of the room-temperature sensing piece, there will be an effect of converting the temperature field into electric field for generating electron current. Thus, the light and thermal electricity generation module has the double functions to convert the light energy and thermal energy into electric energy for increasing the efficiency of the conversion of solar energy into electric energy. Moreover, when the temperature field of temperature damper is converted into an electric field for generating electron current that is conducted out or stored, it has an effect equivalent to that the heat on the heat absorption panel is removed and is kept at the same temperature as that of the room-temperature sensing piece; this will make the solar chip have a high-efficiency heat dissipation effect.
