Jinhui Tong,Jinhui Tong,Zhaoning Song,Dong Hoe Kim,Xihan Chen,Cong Chen,Axel F. Palmstrom,Paul F. Ndione,Matthew O. Reese,Sean P. Dunfield,Sean P. Dunfield,Obadiah G. Reid,Obadiah G. Reid,Jun Liu,Fei Zhang,Steven P. Harvey,Zhen Li,Steven T. Christensen,Glenn Teeter,Dewei Zhao,Mowafak Al-Jassim,Maikel F.A.M. van Hest,Matthew C. Beard,Sean E. Shaheen,Joseph J. Berry,Yanfa Yan,Kai Zhu +26 more
TL;DR: The addition of guanidinium thiocyanate (GuaSCN) resulted in marked improvements in the structural and optoelectronic properties of Sn-Pb mixed, low-band gap perovskite films, enabling the demonstration of >20% efficient low–band gap PSCs.
Journal ArticleDOI
Band Edge Electronic Structure of BiVO4: Elucidating the Role of the Bi s and V d Orbitals
TL;DR: In this paper, the first principles of the electronic structure of BiVO4, a promising photocatalyst for hydrogen generation, were reported, which is a direct band gap semiconductor, despite having band extrema away from the Brillouin zone center.
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
CdTe solar cells with open-circuit voltage breaking the 1 V barrier
James M. Burst,Joel N. Duenow,David S. Albin,Eric Colegrove,Matthew O. Reese,Jeffery A. Aguiar,Chun-Sheng Jiang,Maulik K. Patel,Mowafak Al-Jassim,Darius Kuciauskas,Santosh K. Swain,Tursun Ablekim,Kelvin G. Lynn,Wyatt K. Metzger +13 more
TL;DR: In this paper, the lifetime of single-crystal CdTe solar cells was shown to be comparable to those in GaAs over a hole density range relevant for solar applications.
