Journal ArticleDOI
Overcoming the electroluminescence efficiency limitations of perovskite light-emitting diodes.
Himchan Cho,Su Hun Jeong,Min-Ho Park,Young-Hoon Kim,Christoph Wolf,Chang-Lyoul Lee,Jin Hyuck Heo,Aditya Sadhanala,NoSoung Myoung,Seunghyup Yoo,Sang Hyuk Im,Richard H. Friend,Tae-Woo Lee +12 more
TL;DR: Efficient organic-inorganic perovskite light-emitting diodes were made with nanograin crystals that lack metallic lead, which helped to confine excitons and avoid their quenching.
Journal ArticleDOI
Efficient thin-film organic solar cells based on pentacene/C60 heterojunctions
TL;DR: In this article, an efficient organic photovoltaic cell based on a heterojunction of pentacene and C60 was fabricated, which exhibited broad light-harvesting throughout the visible spectrum with a peak external quantum efficiency (EQE) of 58±4% at short-circuit condition.
Journal ArticleDOI
Comprehensive defect suppression in perovskite nanocrystals for high-efficiency light-emitting diodes
Young-Hoon Kim,Sung-Jin Kim,Arvin Kakekhani,Jinwoo Park,Jaehyeok Park,Yong Hee Lee,Hengxing Xu,Satyawan Nagane,Robert B. Wexler,Dong Hyeok Kim,Seung Hyeon Jo,Laura Martínez-Sarti,Peng Tan,Peng Tan,Aditya Sadhanala,Aditya Sadhanala,Gyeong Su Park,Young-Woon Kim,Bin Hu,Henk J. Bolink,Seunghyup Yoo,Richard H. Friend,Andrew M. Rappe,Tae-Woo Lee +23 more
TL;DR: In this paper, a one-dopant alloying strategy was proposed to generate smaller, monodisperse colloidal particles (confining electrons and holes, and boosting radiative recombination) with fewer surface defects.
Journal ArticleDOI
Built-In Haze Glass-Fabric Reinforced Siloxane Hybrid Film for Efficient Organic Light-Emitting Diodes (OLEDs)
Young-Woo Lim,O Eun Kwon,Seung-Mo Kang,Hyunsu Cho,Jonghee Lee,Young Sam Park,Nam Sung Cho,Won-Yong Jin,Jaeho Lee,Hyunhwan Lee,Jae-Wook Kang,Seunghyup Yoo,Jaehyun Moon,Byeong-Soo Bae +13 more
TL;DR: In this paper, a facile route to fabricate a built-in haze glass-fabric reinforced siloxane hybrid (GFRH) film having high total transmittance and high haze was reported using the scattering effect induced by refractive index contrast between the glass fabric and the hybrimer.
Journal ArticleDOI
Multifunctional materials for implantable and wearable photonic healthcare devices.
Geon-Hui Lee,Geon-Hui Lee,Hanul Moon,Hanul Moon,Hyemin Kim,Gae Hwang Lee,Gae Hwang Lee,Woosung Kwon,Seunghyup Yoo,David Myung,Seok Hyun Yun,Zhenan Bao,Sei Kwang Hahn,Sei Kwang Hahn +13 more
TL;DR: This Review describes emerging multifunctional materials critical to the advent of next-generation implantable and wearable photonic healthcare devices and discusses the path for their clinical translation, along with the future research directions for the field, particularly regarding mobile healthcare and personalized medicine.
