Journal ArticleDOI
An effective and economical encapsulation method for trapping lead leakage in rigid and flexible perovskite photovoltaics
Zhen Li,Xin Wu,Sheng Wu,Danpeng Gao,Hua Dong,Fuzhi Huang,Xiaotian Hu,Alex K.-Y. Jen,Zong Hua Zhu +8 more
TL;DR: In this article , a facile and economical encapsulation process is developed for the first time by employing the mixture of a cation-exchange resin (CER) and an ultraviolet resin as an encapsulant for coating on the metal-side of both rigid and flexible perovskite photovoltaic (PV) devices to effectively capture the leaked Pb2+.
Journal ArticleDOI
A novel benzoxazole-containing poly(N-isopropylacrylamide) copolymer as a multifunctional sensing material
Chang Chung Yang,Chang Chung Yang,Chang Chung Yang,Yanqing Tian,Ching Yi Chen,Alex K.-Y. Jen,Wen-Chang Chen +6 more
TL;DR: In this article, a novel multifunctional material, poly(N-isopropylacrylamide) (PNIPAAm) containing 2-(2-hydroxyphenyl)benzoxazole (HPBO), for sensing pH, zinc ion concentration, or temperature was reported.
Journal ArticleDOI
PCBM-doped electro-optic materials: investigation of dielectric, optical and electro-optic properties for highly efficient poling
Jieyun Wu,Jieyun Wu,Jingdong Luo,Nathan Cernetic,Kaixin Chen,Kin Seng Chiang,Kin Seng Chiang,Alex K.-Y. Jen +7 more
TL;DR: In this paper, PCBM was doped into organic electro-optic (EO) materials and their surface morphology, photophysical properties, dielectric properties as well as optical properties (refractive index) were systematically investigated.
Journal ArticleDOI
Rational Design of Organic Electro-Optic Materials
TL;DR: In this paper, an improved understanding of the structure/function relationships of organic electro-optic materials has been exploited for the development of new materials and their incorporation into photonic bandgap and microresonator structures.
Journal ArticleDOI
Asymmetric Isomer Effects in Benzo[c ][1,2,5]thiadiazole-Fused Nonacyclic Acceptors: Dielectric Constant and Molecular Crystallinity Control for Significant Photovoltaic Performance Enhancement
Wei Gao,Baobing Fan,Feng Qi,Francis Lin,Francis Lin,Rui Sun,Xinxin Xia,Jinhua Gao,Cheng Zhong,Xinhui Lu,Jie Min,Fujun Zhang,Zonglong Zhu,Jingdong Luo,Alex K.-Y. Jen,Alex K.-Y. Jen +15 more
TL;DR: Asymmetric isomerization from BP6T‐4F to ABP6T•4F not only lowers the exciton bonding energy but optimizes the crystallization performance, achieving a pronounced isomer effect with 9.4% power conversion efficiency enhancement.
