Abstract

The invention relates to an all-weather continuous power generation device capable of being assembled in a modular mode, which comprises a radiation refrigerating device, a photo-thermal conversion device, a thermoelectric conversion device and a heat conduction substrate which are assembled and connected in a modular mode, the thermoelectric conversion device is arranged on a heat conduction substrate, and the radiation refrigerating device and the photo-thermal conversion device are respectively connected with the thermoelectric conversion device in a heat transfer manner. Compared with the prior art, the power generation device is not limited by time and regions, can generate power by utilizing the temperature difference between the photo-thermal conversion device and the radiation refrigeration device in the daytime and can generate power by utilizing the radiation refrigeration device and the environment temperature on the surface of the earth at night, and the device structure and size can be designed and can be modularly assembled according to the environment characteristics; and the utilization of energy is maximized.

Description

technical field [0001] The invention belongs to the technical field of energy conversion and application, and in particular relates to an all-weather continuous power generation device which can be assembled in modules. Background technique [0002] Developing clean energy to reduce dependence on fossil fuels is one of the effective ways to solve energy shortages and reduce pollutant emissions. Solar energy is the most widely distributed energy on the earth. Using photovoltaic (photovoltaic cells) and photothermoelectric effects (photothermal materials + thermoelectric devices) to convert the light energy in solar energy into electrical energy is an effective way to obtain clean energy. For example, patent application CN110086418A discloses a photovoltaic power generation device, patent application CN110274326A discloses a daytime radiant refrigerator and its preparation method, and patent application CN111486069A discloses an energy management device for a solar-assisted oc...
