Abstract
The carrier mobility of C60-doped hole transport layer was investigated according to the C60 content. The addition of C60 in the 1, 3, 5-tris (N, N-bis-(4, 5-methoxyphenyl)-aminophenyl) benzol (TDAPB) hole transport material resulted in the increase of hole mobility of TDAPB. The C60 molecule acted as a p -type dopant in the hole transport layer, resulting in the improved hole transport in TDAPB. The hole mobility of C60-doped TDAPB was 9.0× 10-4 cm2 Vs compared with 1.0× 10-4 cm2 Vs for nondoped TDAPB.
