NiOx/SAM & New products
for High-efficiency and Long-life Perovskite solar cell.
Nickel oxide nanoparticle has relatively good stability. In recent years, some Science papers have shown that NiOx is used in combination with self-assembled mono-molecular material (SAM) as hole-transporting layer. Through interface modification, the performance of perovskite solar device is improved. Power conversion efficiency and operating life have been significantly improved.

Hybridized Local and Charge-Transfer (HLCT) Molecule for OLED
High-efficiency deep-blue non-doped OLED and hybrid white OLED can be made by using a novel multifunctional HLCT host emitter PPIS (LT-N4252). The high luminance and reduced efficiency roll-off at high current density are achieved owing to higher charge mobility. The non-doped deep blue device shows EQE 6.68% at CIE(0.156, 0.090). Also, high EQE and PE exceeding 26.8% and 95 lm/W are realized without out-coupling for a two-color hybrid white OLED.
