Abstract

The invention belongs to the technical field of solar cells, and particularly relates to a perovskite solar cell capable of being spliced and a preparation method thereof. On the basis of an electrode capable of being spliced prepared by aligned carbon nanotubes and self-repair polymers, a perovskite solar cell capable of being spliced with good flexibility and photoelectric conversion efficiency can be prepared. A strong hydrogen bonding effect can be formed between the self-repair polymers and an indium tin oxide electrode, the aligned carbon nanotubes and the indium tin oxide electrode are contacted and firmly spliced together, a simple and convenient serial connection is realized, and no any wire or circuit is needed. The solar cell obtained after splicing has good flexibility and structural stability, and can be widely applied to fields such as a flexible device, a wearable device and a portable energy device.

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...
