| titleOfInvention | A stable perovskite solar cell and preparation method thereof |
| abstract | The invention provides a stable perovskite solar cell and a preparation method thereof. The problems of instability and easy water absorption and decomposition of the existing perovskite solar cell are solved by adding a small amount of hydrophobic polymer in the perovskite light absorbing layer. The perovskite solar cells provided by the present invention are divided into two types: formal and trans, according to different structures. The perovskite light-absorbing layers are all ABX 3 structures, and the doped hydrophobic material is polydimethylsiloxane (silicone oil). ), amino silicone oil, polyethylene oxide silicone oil (PEG silicone oil), and polyethylene glycol, and the doping amount of the hydrophobic substance is not higher than 5wt% of the perovskite solution. The invention starts from the perovskite decomposition principle, and the prepared perovskite solar cell has more stable performance in the air. |
