Photocapacitor is integrated with perovskite solar cell and symmetrical supercapacitor. The energy matching between the conversion unit and the storage unit is harmonized. Photocapacitor achieves milestone conversion storage efficiency as high as 20.53 %. Photo-electron-chemical process and efficiency in device are clarified and defined.
Using perovskite solar cell as energy conversion unit and symmetrical supercapacitor as energy storage unit, an integrated photocapacitor (IPC) is designed.
Photocapacitor achieves milestone conversion storage efficiency as high as 20.53 %. Photo-electron-chemical process and efficiency in device are clarified and defined. Solar energy is clean, open, and infinite, but solar radiation on the earth is fluctuating, intermittent, and unstable.
By exploring new materials, refining device architectures, and integrating with advanced technologies such as machine learning and artificial intelligence, photocapacitors have the potential to reshape numerous sectors and contribute to a more sustainable and connected future.
The deployment of photocapacitors in self-powered electronic devices could lead to significant societal benefits, such as energy savings, increased use of renewable energy, enhanced connectivity, and improved data transfer.
Fabrication of integrated photocapacitors The conductive silver paste is coated as thinly as possible on both sides of the copper foil with a glass sheet to make Janus electrodes. The Au electrode of PSC and the current collector of SSC are stacked on both sides of the Janus electrode, respectively.
