Self-Assembled Monolayer Treated ZnO by Benzoic Acid Derivatives in Organic Solar Cells |
| 초록 |
Self-assembled monolayer (SAM) molecule derivatives from benzoic acid, such as 4-methoxybenzoic acid (MBA), 4-tertbutylbenzoic acid (BBA), and 4-fluorobenzoic acid (FBA), have different dipole orientation and magnitude. In this study, these benzoic acid derivatives were used as an electron injection/transporting layer in inverted type organic solar cells (OSCs) with a structure of ITO/SAM treated ZnO/active layer (P3HT:PC61BM)/MoO3/Ag, and then the performances of each are compared. The results showed that the power conversion efficiency (PCE) and the open circuit voltage (Voc) values of the devices based on ZnO/MBA and ZnO/BBA treated ZnO showed better performances than other devices. This can be caused by the direction of dipole moment of benzoic acid derivatives. Accordingly, this work provides an alternative strategy to improve the interface property between inorganic and organic materials in organic electronic devices by SAM treatment on the ZnO surface |
