Dongqin Bi,Wolfgang Tress,M. Ibrahim Dar,Peng Gao,Jingshan Luo,Clementine Renevier,Kurt Schenk,Antonio Abate,Fabrizio Giordano,Juan-Pablo Correa Baena,Jean-David Decoppet,Shaik M. Zakeeruddin,Mohammad Khaja Nazeeruddin,Michael Grätzel,Anders Hagfeldt +14 more
TL;DR: A new metal halide perovskite photovoltaic cell that exhibits both very high solar-to-electric power-conversion efficiency and intense electroluminescence is reported on.
Journal ArticleDOI
Perovskite solar cells with CuSCN hole extraction layers yield stabilized efficiencies greater than 20
Neha Arora,M. Ibrahim Dar,Alexander Hinderhofer,Norman Pellet,Frank Schreiber,Shaik M. Zakeeruddin,Michael Grätzel +6 more
TL;DR: Th Thin CuSCN films can replace organic hole-transporting layers that limit thermal stability of devices and demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the hole extraction layer.
Journal ArticleDOI
Improved performance and stability of perovskite solar cells by crystal crosslinking with alkylphosphonic acid ω-ammonium chlorides.
Xiong Li,M. Ibrahim Dar,Chenyi Yi,Jingshan Luo,Manuel Tschumi,Shaik M. Zakeeruddin,Mohammad Khaja Nazeeruddin,Hongwei Han,Michael Grätzel +8 more
TL;DR: A one-step solution-processing strategy using phosphonic acid ammonium additives that results in efficient perovskite solar cells with enhanced stability, enhancing the material's photovoltaic performance from 8.8 to 16.7% as well as its resistance to moisture.
Journal ArticleDOI
Thermodynamically stabilized β-CsPbI3-based perovskite solar cells with efficiencies >18.
Yong Wang,M. Ibrahim Dar,Luis K. Ono,Taiyang Zhang,Miao Kan,Yawen Li,Lijun Zhang,Xingtao Wang,Yingguo Yang,Xingyu Gao,Yabing Qi,Michael Grätzel,Yixin Zhao +12 more
TL;DR: High crystalline β-CsPbI3 films are obtained with an extended spectral response and enhanced phase stability and made from the treated material have highly reproducible and stable efficiencies reaching 18.4% under 45 ± 5°C ambient conditions.
Journal ArticleDOI
Bication lead iodide 2D perovskite component to stabilize inorganic α-CsPbI 3 perovskite phase for high-efficiency solar cells
TL;DR: It is discovered that a small amount of two-dimensional EDAPbI4 perovskite containing the ethylenediamine (EDA) cation stabilizes the α-CsPbI3 to avoid the undesirable formation of the nonperovskites δ phase.
