The invention relates to a self-charging miniature photocapacitor device and a preparation method thereof, belonging to the technical field of energy storage devices. The photocapacitor device includes a micro supercapacitor, a perovskite solar cell, a shared negative electrode wire, a shared positive electrode wire, a series wire, an encapsulation material, and an electrolyte, and a perovskite solar cell is realized on the same piece of conductive glass through clever graphic design The seamless connection with micro supercapacitors reduces the internal resistance; through the compatibility between activated carbon, RGO, PEDOT and electrolyte, the structural parameters of perovskite solar cells and micro supercapacitors can also be optimized, and the The series integration of multiple perovskite solar cells can realize the large capacitance, high energy density and excellent high current charge-discharge performance of the photocapacitor device; in addition, the preparation process of the photocapacitor device is simple and can be fabricated on a large scale Moreover, it is small in size, green and environmentally friendly, and has a good application prospect. |
