Abstract

The invention proposes a perovskite solar cell-super capacitor combined energy conversion and storage integrated device and belongs to the energy conversion and storage technical field. The integrated device comprises a transparent electric conduction substrate, an electron transport layer, a perovskite light absorption layer, a dual-function layer, an electrolyte layer and an upper electrode layer of a super capacitor which are arranged sequentially from bottom to top, wherein the dual-function layer is simultaneously adopted as a hole transport layer of a perovskite solar cell and a lower electrode layer of the super capacitor. According to the perovskite solar cell-super capacitor combined energy conversion and storage integrated device of the invention, the perovskite solar cell and the super capacitor can be combined through the material of the dual-function layer which can be either adopted as the material of the hole transport layer of the perovskite solar cell or the electrode material of the lower electrode of the super capacitor, and therefore, an energy conversion function and a storage function can be realized, and the thickness of the device can be decreased, and a preparation process can be simplified, and cost can be reduced, and the realization of miniaturized electronic equipment can be benefitted.

Description
