Journal ArticleDOI
All-perovskite tandem solar cells with 24.2% certified efficiency and area over 1 cm2 using surface-anchoring zwitterionic antioxidant
Ke Xiao,Renxing Lin,Qiaolei Han,Yi Hou,Zhenyuan Qin,Hieu T. Nguyen,Jin Wen,Mingyang Wei,Vishal Yeddu,Makhsud I. Saidaminov,Yuan Gao,Xin Luo,Y.N. Wang,Han Gao,Chunfeng Zhang,Jun Xu,Jia Zhu,Edward H. Sargent,Hairen Tan +18 more
TL;DR: Xiao et al. as mentioned in this paper used strongly reductive surface-anchoring zwitterionic molecules to suppress Sn2+ oxidation and passivate defects at the grain surfaces in mixed lead-tin perovskite films, enabling an efficiency of 21.7% (certified 20.7%).
Journal ArticleDOI
Interface passivation using ultrathin polymer–fullerene films for high-efficiency perovskite solar cells with negligible hysteresis
Jun Peng,Yiliang Wu,Wang Ye,Daniel A. Jacobs,Heping Shen,Xiao Fu,Yimao Wan,Nandi Wu,Chog Barugkin,Hieu T. Nguyen,Dingyong Zhong,Juntao Li,Teng Lu,Yun Liu,Mark Lockrey,Klaus Weber,Kylie R. Catchpole,Thomas P. White,Thomas P. White +18 more
TL;DR: In this article, an ultrathin passivation layer consisting of a PMMA:PCBM mixture was proposed to suppress interfacial recombination at or near the perovskite/TiO2 interface.
Journal ArticleDOI
Uncertainty analysis for the coefficient of band-to-band absorption of crystalline silicon
Carsten Schinke,P. Christian Peest,Jan Schmidt,Rolf Brendel,Karsten Bothe,Malte R. Vogt,I. Kröger,S. Winter,Alfred Schirmacher,Siew Yee Lim,Hieu T. Nguyen,Daniel Macdonald +11 more
TL;DR: In this article, the uncertainty of the band-to-band absorption coefficient of crystalline silicon was analyzed using the Guide to the expression of uncertainty in measurement (GUM) as well as an extensive characterization of the measurement setups.
Journal ArticleDOI
Nanoscale localized contacts for high fill factors in polymer-passivated perovskite solar cells
Jun Peng,Daniel Walter,Yuhao Ren,Mike Tebyetekerwa,Yiliang Wu,Qiaoling Lin,Juntao Li,Teng Lu,Arafat Mahmud,Olivier Lee Cheong Lem,Shenyou Zhao,Wenzhu Liu,Yun Liu,Heping Shen,Li Li,Felipe Kremer,Hieu T. Nguyen,Duk-Yong Choi,Klaus Weber,Kylie R. Catchpole,Thomas P. White +20 more
TL;DR: A nanopatterned electron transport layer is introduced that overcomes this trade-off by modifying the spatial distribution of the passivation layer to form nanoscale localized charge transport pathways through an otherwise passivated interface, thereby providing both effective passivation and excellent charge extraction.
Journal ArticleDOI
Structural engineering using rubidium iodide as a dopant under excess lead iodide conditions for high efficiency and stable perovskites
Hemant Kumar Mulmudi,Heping Shen,Yiliang Wu,Chog Barugkin,Yahuitl Osorio Mayon,Hieu T. Nguyen,Daniel Macdonald,Jun Peng,Mark Lockrey,Wei Li,Yi-Bing Cheng,Thomas P. White,Klaus Weber,Kylie R. Catchpole +13 more
TL;DR: In this paper, the performance of RbI-doped perovskite cells is reported for the first time with the highest efficiency of 18.8% and improved thermal/photo stability compared to the undoped cells.
