Tris(4-(1-phenyl-1H-benzo[d]imidazole)phenyl)phosphineoxide for Enhanced Mobility and Restricted Traps in Photovoltaic Interlayers |
| 초록 |
As small molecule organic materials,Tris(4-(1-phenyl-1H-benzo[d]imidazole)phenyl)phosphine oxide(TIPO) and Tris(4-(1-phenyl-1H-benzo[d]imidazole)phenyl)triazine(TBIT) were newly synthesized and applied to n-type interlayer of planarperovskite solar cells (PSCs) for effective electron transport layer. Themolecule materials contained phenyl benzimidazole group which is combined witha phosphine oxide core or triazine ring core and has contributed to the enhancementof charge extraction and stability. Since the constituent molecules phosphineoxide and benzimidazole (BIZ) have high polarity and strong π-electrons, themolecules trigger passivation defects to improve charge transport andflattening the surface morphology. In addition, the stability of the device wasimproved by introducing TIPO material as the passivation and protection layer. |
