Composite power source device based on solar battery and thermobattery

The invention discloses a composite power source device based on solar batteries and thermobatteries, belonging to the technical field of electron devices, and relating to a solar battery and a thermobattery. The invention integrates the dye-sensitized solar battery with the thermoelectric thermobattery and additionally arranges a transparent thermal-protective layer and a solar energy thermal collecting layer between two units so as to fully adsorb near-infrared in sunlight; the thermal transmission of the whole device is effectively controlled to comprehensively and efficiently utilize each wave band of sunlight, and solar battery and solar energy thermal collecting thermoelectricity are integrated to greatly improve the utilization efficiency of solar energy. Compared with the existing photovoltaic/ thermoelectric integrated devices, the device adopts the dye-sensitized solar battery with low cost and utilizes the advantage of transmission of light to obtain higher photoelectric conversion on the basis of simpler construction and technology. The invention can serve as a portable power source device with small volume and low power and is suitable for large-area production and use.
