Journal ArticleDOI
Additive manufacturing of metallic components – Process, structure and properties
Tarasankar Debroy,Huiliang Wei,J.S. Zuback,T. Mukherjee,John W. Elmer,John O. Milewski,Allison M. Beese,Alexander E. Wilson-Heid,Amitava De,Wei Zhang +9 more
TL;DR: A review of the emerging research on additive manufacturing of metallic materials is provided in this article, which provides a comprehensive overview of the physical processes and the underlying science of metallurgical structure and properties of the deposited parts.
Journal ArticleDOI
Anomalous hysteresis in perovskite solar cells
Henry J. Snaith,Antonio Abate,James M. Ball,Giles E. Eperon,Tomas Leijtens,Nakita K. Noel,Samuel D. Stranks,Jacob Tse-Wei Wang,Konrad Wojciechowski,Wei Zhang +9 more
TL;DR: This work identifies an anomalous hysteresis in the current-voltage curves of perovskite solar cells, hypothesizes three possible origins of the effect, and discusses its implications on device efficiency and future research directions.
Journal ArticleDOI
Enhanced photovoltage for inverted planar heterojunction perovskite solar cells
Deying Luo,Wenqiang Yang,Zhiping Wang,Aditya Sadhanala,Qin Hu,Rui Su,Ravichandran Shivanna,Gustavo F. Trindade,John F. Watts,Zhaojian Xu,Tanghao Liu,Ke Chen,Fengjun Ye,Pan Wu,Lichen Zhao,Jiang Wu,Yongguang Tu,Yifei Zhang,Xiao-Yu Yang,Wei Zhang,Richard H. Friend,Qihuang Gong,Qihuang Gong,Henry J. Snaith,Rui Zhu,Rui Zhu +25 more
TL;DR: This approach produces a wider bandgap top layer and a more n-type perovskite film, which mitigates nonradiative recombination, leading to an increase in Voc by up to 100 millivolts, which led to a stabilized power output approaching 21% at the maximum power point.
Journal ArticleDOI
Ultrasmooth organic-inorganic perovskite thin-film formation and crystallization for efficient planar heterojunction solar cells.
Wei Zhang,Michael Saliba,David T. Moore,Sandeep Pathak,Maximilian T. Hörantner,Thomas Stergiopoulos,Samuel D. Stranks,Giles E. Eperon,Jack A. Alexander-Webber,Antonio Abate,Aditya Sadhanala,Shuhua Yao,Yulin Chen,Richard H. Friend,Lara A. Estroff,Ulrich Wiesner,Henry J. Snaith +16 more
TL;DR: It is found that by using a non-halide lead source (lead acetate) instead of lead chloride or iodide, the perovskite crystal growth is much faster, which allows us to obtain ultrasmooth and almost pinhole-free perovSKite films by a simple one-step solution coating with only a few minutes annealing.
Journal ArticleDOI
Photo-induced halide redistribution in organic–inorganic perovskite films
Dane W. deQuilettes,Wei Zhang,Victor M. Burlakov,Daniel J. Graham,Tomas Leijtens,Anna Osherov,Vladimir Bulovic,Henry J. Snaith,David S. Ginger,Samuel D. Stranks +9 more
TL;DR: This work provides visual evidence for photo-induced halide migration in triiodide perovskites and reveals the complex interplay between charge carrier populations, electronic traps and mobile halides that collectively impact optoelectronic performance.
