Journal ArticleDOI
Efficient tandem solar cells with solution-processed perovskite on textured crystalline silicon.
Yi Hou,Erkan Aydin,Michele De Bastiani,Chuanxiao Xiao,Furkan Halis Isikgor,Ding-Jiang Xue,Bin Chen,Hao Chen,Behzad Bahrami,Ashraful Haider Chowdhury,Andrew Johnston,Se-Woong Baek,Ziru Huang,Mingyang Wei,Yitong Dong,Joel Troughton,Rawan Jalmood,Alessandro J. Mirabelli,Thomas Allen,Emmanuel Van Kerschaver,Makhsud I. Saidaminov,Derya Baran,Qiquan Qiao,Kai Zhu,Stefaan De Wolf,Edward H. Sargent +25 more
TL;DR: Tandems that combine solution-processed micrometer-thick perovskite top cells with fully textured silicon heterojunction bottom cells are reported, which presents the possibility of overcoming the single-junction Shockley-Queisser limit in photovoltaics.
Journal ArticleDOI
Employing Lead Thiocyanate Additive to Reduce the Hysteresis and Boost the Fill Factor of Planar Perovskite Solar Cells.
Weijun Ke,Weijun Ke,Weijun Ke,Chuanxiao Xiao,Changlei Wang,Bayrammurad Saparov,Hsin-Sheng Duan,Dewei Zhao,Dewei Zhao,Zewen Xiao,Philip Schulz,Steven P. Harvey,Wei-Qiang Liao,Weiwei Meng,Yue Yu,Alexander J. Cimaroli,Chun-Sheng Jiang,Kai Zhu,Mowafak Al-Jassim,Guojia Fang,David B. Mitzi,Yanfa Yan +21 more
TL;DR: Lead thiocyanate in the perovskite precursor can increase the grain size of a perovSkite thin film and reduce the conductivity of the grain boundaries, leading to perovkite solar cells with reduced hysteresis and enhanced fill factor.
Journal ArticleDOI
Extrinsic ion migration in perovskite solar cells
Zhen Li,Chuanxiao Xiao,Chuanxiao Xiao,Ye Yang,Steven P. Harvey,Dong Hoe Kim,Jeffrey A. Christians,Mengjin Yang,Philip Schulz,Sanjini U. Nanayakkara,Chun-Sheng Jiang,Joseph M. Luther,Joseph J. Berry,Matthew C. Beard,Mowafak Al-Jassim,Kai Zhu +15 more
TL;DR: In this paper, the authors demonstrate that extrinsic ions (e.g., Li+, H+, Na+), when used in the contact layers in PSCs, can migrate across the perovskite layer and strongly impact PSC operation.
Journal ArticleDOI
Efficient, stable silicon tandem cells enabled by anion-engineered wide-bandgap perovskites
Daehan Kim,Hee Joon Jung,Ik Jae Park,Bryon W. Larson,Sean P. Dunfield,Sean P. Dunfield,Chuanxiao Xiao,Jekyung Kim,Jinhui Tong,Passarut Boonmongkolras,Su Geun Ji,Fei Zhang,Seong Ryul Pae,Minkyu Kim,Seok Beom Kang,Vinayak P. Dravid,Joseph J. Berry,Joseph J. Berry,Jin Young Kim,Kai Zhu,Dong Hoe Kim,Dong Hoe Kim,Byungha Shin +22 more
TL;DR: It is shown that by using phenethylammonium as a two-dimensional additive, along with iodine and thiocyanate, bromine-rich perovskite films can be stabilized and, by doing so, improve the carrier mobility and stability in silicon tandem solar cells.
Journal ArticleDOI
High efficiency perovskite quantum dot solar cells with charge separating heterostructure.
Qian Zhao,Abhijit Hazarika,Xihan Chen,Steve Harvey,Bryon W. Larson,Glenn Teeter,Jun Liu,Tao Song,Chuanxiao Xiao,Liam Shaw,Minghui Zhang,Guo-Ran Li,Matthew C. Beard,Joseph M. Luther +13 more
TL;DR: Zhao et al. fabricate heterojunctions of colloidal perovskite quantum dots with different composition using layer-by-layer deposition and demonstrate improved photovoltaic performance with enhanced photocarrier harvesting.
