Problems solved by technology

[0007] At present, there are relatively many related studies on the integration of solar cells and supercapacitors, but the research on the integration of perovskite solar cells with supercapacitors and thermoelectric devices is still blank, and the existing integration methods are simple, the process is complicated, and most of them need to go through high temperature. It is not suitable for large-scale practical applications, especially in the field of flexible electronics manufacturing that is currently widely concerned.
[0008] In view of the above technical problems, there is no perovskite solar cell micro-integrated device with excellent light absorption performance, rapid and stable charge and discharge, and simple structure. Spectral absorption, as well as the effective storage and stable output of energy in micro-integrated devices, the manufacture of highly integrated high-efficiency perovskite solar cell integrated devices, and further application to flexible electronic products are the problems to be solved by the present invention

technical field [0001] The invention belongs to the technical field of miniature energy conversion and storage devices, and specifically relates to a perovskite solar cell integrated device and a preparation method thereof, which can improve photoelectric conversion efficiency, increase the storage capacity of electric energy, and improve the stability of electric energy storage and output. Background technique [0002] With the development of the current world industry and the continuous growth of population, the demand for global energy is also increasing rapidly, especially for non-renewable resources such as oil, coal, and natural gas. Due to the over-exploitation and utilization of fossil energy by human beings, such energy reserves are on the verge of exhaustion. At the same time, with the continuous consumption of fossil energy, a large amount of pollutants are discharged into nature, and the environmental problems brought about are becoming more and more severe. The...
