Journal ArticleDOI
Perovskite light-emitting diodes with external quantum efficiency exceeding 20 per cent
Kebin Lin,Jun Xing,Li Na Quan,F. Pelayo García de Arquer,Xiwen Gong,Jianxun Lu,Liqiang Xie,Weijie Zhao,Di Zhang,Chuanzhong Yan,Wenqiang Li,Xinyi Liu,Yan Lu,Jeffrey Kirman,Edward H. Sargent,Qihua Xiong,Zhanhua Wei +16 more
TL;DR: In this article, the authors describe visible-light-emitting perovskite LEDs that surpass the quantum efficiency milestone of 20.3 per cent, which is achieved by a new strategy for managing the compositional distribution in the device.
Journal ArticleDOI
Hybrid graphene-quantum dot phototransistors with ultrahigh gain
Gerasimos Konstantatos,Michela Badioli,Louis Gaudreau,Johann Osmond,Maria Bernechea,F. Pelayo García de Arquer,Fabio Gatti,Frank H. L. Koppens +7 more
TL;DR: A gain of ∼10(8) electrons per photon and a responsivity of ∼ 10(7) A W(-1) in a hybrid photodetector that consists of monolayer or bilayer graphene covered with a thin film of colloidal quantum dots is demonstrated.
Journal ArticleDOI
Efficient and stable solution-processed planar perovskite solar cells via contact passivation.
Hairen Tan,Ankit Jain,Oleksandr Voznyy,Xinzheng Lan,F. Pelayo García de Arquer,James Z. Fan,Rafael Quintero-Bermudez,Mingjian Yuan,Bo Zhang,Yicheng Zhao,Fengjia Fan,Peicheng Li,Li Na Quan,Yongbiao Zhao,Zheng-Hong Lu,Zhenyu Yang,Sjoerd Hoogland,Edward H. Sargent +17 more
TL;DR: A contact-passivation strategy using chlorine-capped TiO2 colloidal nanocrystal film that mitigates interfacial recombination and improves interface binding in low-temperature planar solar cells is reported.
Journal ArticleDOI

Hybrid graphene-quantum dot phototransistors with ultrahigh gain
Gerasimos Konstantatos,Michela Badioli,Louis Gaudreau,Johann Osmond,Maria Bernechea,F. Pelayo García de Arquer,Fabio Gatti,Frank H. L. Koppens +7 more
TL;DR: In this article, the authors exploit the strong light absorption in quantum dots and the two-dimensionality and high mobility of graphene to merge these materials into a hybrid system for photodetection with extremely high sensitivity.
