Problems solved by technology

However, the output of perovskite solar cells will fluctuate with the change of sunlight, especially in the environment where the light is unstable, it is difficult to stabilize the output.
This has led to the fact that perovskite solar cells are currently unable to replace lithium-ion batteries to directly power portable electronics.

Abstract

The invention provides a method for making a photocapacitor. The method comprises the steps such as: preparing a perovskite solar cell, preparing a first supercapacitor electrode, and deposing and dissolving the first supercapacitor electrode with the perovskite solar cell. The photocapacitor obtained by the method provided by the invention has obvious improvement on electrical properties, is suitable for various light fluctuation environments, and has stable structure and longer service life.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a photoelectric energy storage device and a preparation method thereof. Background technique [0002] In recent years, solar cells based on perovskite materials (referred to as perovskite solar cells for short) have achieved leapfrog development. However, the output of perovskite solar cells will fluctuate with the change of sunlight, especially in an environment with unstable light, it is difficult to stabilize the output. This has led to the fact that perovskite solar cells are currently unable to replace lithium-ion batteries to directly power portable electronics. Contents of the invention [0003] In view of this, it is indeed necessary to provide a method for preparing a photoelectric self-storage device to overcome the defects in the prior art. [0004] Compared with the prior art, the electrical properties of the photoelectric self-storage device provid...
