Interfacial engineering towards stable and safe lead perovskite solar cell |
| 초록 |
The spiro-MeOTAD is most popular hole transport materials due to its high peroforman on the perovskite solar cell. To obtain effective hole mobility, Li-TFSI, a p-type dopant, is always employed into the spiro-MeOTAD matrix. However, this added Li cation moves into the electron transport layer (ETL) when bias is applied to the solar cell, which eventually degrades the stability of the perovskite solar cell. Therefore, in this study, we investigate new interfacial materials between perovskite and HTL which enable capture free Li ion to prevent degradation of the long-term stability and improve photovoltaic performance. |
