Application	VNPB is designed as a versatile Hole Transport / Electron Blocking Layer (HTL / EBL) material, commonly applied in the realm of organic electronics, including OLEDs and perovskite solar cells. Its implementation in OLED devices has resulted in significant enhancements, elevating maximum current efficiency from 9.7 Cd/A in devices without VNPB to 22.2 Cd/A, while also extending device lifespan by up to 74.8%. VNPB provides a straightforward and additive-free method to avert defect formation in solution-processed thin-film stacks composed of small molecular materials. In the field of solar energy, VNPB has proven effective in boosting open-circuit voltage (VOC) and power conversion efficiency (PCE) in wide-bandgap perovskite solar cells by transitioning the hole transport layer from the typically used PTAA to an in-situ cross-linked small molecular variant. Consequently, power conversion efficiencies of 24.9% in perovskite/perovskite cells and 25.4% in perovskite/silicon tandem solar cells have been achieved.
