| Hazard Information | Back Directory | [Uses]
N4,N4μ-Di(naphthalen-1-yl)-N4,N4μ-bis(4-vinylphenyl)biphenyl-4,4μ-diamine, also known as VNPB, is a solution-processable Hole Transport / Electron Blocking Layer (HTL / EBL) material popularly used in organic electronics, such as OLEDs and perovskite solar cells .
In OLED devices, the use of VNPB enabled the maximum current efficiency of 22.2 Cd/A, compared to 9.7 Cd/A in the reference device without VNPB, and the device lifetime was extended by up to 74.8% . VNPB allowed a simple and additive-free strategy to prevent the formation of defects in solution processed thin-film stacks made of small-molecular materials.
In solar cells, VNPB increased open-circuit voltage (VOC) and power conversion efficiency (PCE) of wide-bandgap perovskite solar cells by changing the hole transport layer (HTL) from commonly used poly(bis(4-phenyl)(2,4,6-trimethylphenyl)amine) (PTAA) to in-situ cross-linked small mol. VNPB . PCEs of 24.9% and 25.4% have been achieved in perovskite/perovskite and perovskite/silicon tandem solar cells, resp. |
