Abstract

The invention belongs to the technical field of solar cells, and in particular relates to a splicable perovskite solar cell and a preparation method thereof. The invention is based on a splicable electrode prepared by aligned carbon nanotubes and self-repairing polymers, and prepares a splicable perovskite solar cell with good flexibility and photoelectric conversion efficiency. The self-healing polymer can form a strong hydrogen bond with the indium tin oxide electrode, so that the aligned carbon nanotubes and the indium tin oxide electrode are in contact and spliced ​​together firmly, realizing a simple series connection without any wires or circuits . The solar cells obtained after splicing have good flexibility and structural stability, and can be widely used in fields such as flexible devices, wearable devices, and portable energy devices.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a splicable perovskite solar cell and a preparation method thereof. Background technique [0002] Energy issues are considered to be one of the most important challenges facing human society in the 21st century. In order to alleviate the energy shortage caused by the depletion of fossil energy, renewable energy such as solar energy, wind energy, and tidal energy have received extensive attention and research. Among them, solar energy has become the most promising energy source among renewable energy due to its inexhaustible characteristics. [1] Although people have conducted extensive and in-depth research on various solar cells, in actual use, solar cells must be connected in series through wires or circuits to increase the output voltage, which greatly increases the production cost and complexity, and may safety issues such as short circuits. Especially when...
