Shengfan Wu,Zhen Li,Jie Zhang,Xin Wu,Xiang Deng,Yiming Liu,Jingkun Zhou,Chunyi Zhi,Xinge Yu,Wallace C. H. Choy,Zonglong Zhu,Alex K.-Y. Jen +11 more
TL;DR: In this article, a low-bandgap organic bulk-heterojunction (BHJ) layer was integrated into inverted lead halide perovskite (PSCs) to construct facile hybrid solar cells (HSCs).
Journal ArticleDOI
Broadband electro-optic polymer modulators with high electro-optic activity and low poling induced optical loss
TL;DR: In this article, a screening method for electro-optic polymers with an emphasis on broadband device suitability was proposed, based on comparing the signal from second harmonic generation (SHG) and the leak through current (LTC) during poling.
Journal ArticleDOI
Red electrophosphorescence from osmium complexes
TL;DR: In this article, the authors reported red electrophosphorescence from light-emitting diodes based on osmium (Os) complexes, using an in situ polymerized tetraphenyldiaminobiphenyl-containing polymer as the hole-transporting layer and Os complexes doped blend of poly(N-vinylcarbazole) and 2-tert-butylphenyl-5-bipenyl-1,3,4-oxadiazole as the emitting layer.

TL;DR: In this article, a series of cross-linkable hole-transporting materials (X-HTMs) consisting of indacenodithiophene, bithiophen, and thiophene units bookended by two triarylamine groups have been designed and synthesized to investigate their suitability as new anode buffer layer for bulk heterojunction polymer solar cells (PSCs).
