Highly-integrated, highly-efficient, environment-friendly and low-cost devices for photo-electrical conversion and energy storage are regarded as promising components in portable devices. Taking advantage of the charge transfer and ion diffusion abilities in nano-hybrid electrode, hybrid electrodes composed of mesoporous carbon and P-type energy storage materials (NiOx, MoO3, etc.) can be used as the shared cathode in perovskite solar cells (PSCs) and electrochemical supercapacitors (ESCs). In this proposal, we would like to build all-in-one photo-supercapacitors based on the delicately designed shared-electrode, in which both the solar energy conversion and storage functions are integrated in one cell. We hypothesize that, by combining the nano-fabrication regulation strategies with printing technology and electrochemical synthesis methods, we can obtain hybrid electrodes with high hole mobility and abundant ion diffusion paths. Meanwhile, the relationship between the composition and photoelectrical, electrochemical properties will also be investigated, which will determine the hole mobility in PSC part and ion diffusion ability in ESC part. Finally, we will focus on the mechanism of charge transportation and synergetic mechanism of charges and ions in the photo-supercapacitor during photo charging process, aiming at an achievement of high photoelectric conversion efficiency, energy storage efficiency and energy density. We believe that this research will provide some theoretical foundation for the designation of highly-efficient, low-loss and low-cost integrated system, and bring important advance to the area of energy conversion and storage.
