Yingguo Yang,Haizhou Lu,Shanglei Feng,Lifeng Yang,Hua Dong,Jiaou Wang,Chen Tian,Lina Li,Hong-Liang Lu,Jaeki Jeong,Shaik M. Zakeeruddin,Yuhang Liu,Michael Grätzel,Anders Hagfeldt +13 more
TL;DR: In this paper, an in situ synchrotron-based two-dimensional grazing-incidence X-ray diffraction technique was used to explore the SnO2 ETL-modulated perovskite crystallization kinetics for the first time.
Journal ArticleDOI
An Efficient Dye‐Sensitized Solar Cell with an Organic Sensitizer Encapsulated in a Cyclodextrin Cavity
Hyunbong Choi,Sang Ook Kang,Jaejung Ko,Guohua Gao,Hong Seok Kang,Moon-Sung Kang,Md. K. Nazeeruddin,Michael Grätzel +7 more
TL;DR: The chiral stationary phase for high-performance liquid chromatography showed good chiral recognition ability towards various racemates, including Ruthenium Sensitizer and Dendrimers.
Journal ArticleDOI
Effect of anchoring groups in zinc phthalocyanine on the dye-sensitized solar cell performance and stability
Miguel García-Iglesias,Jun-Ho Yum,Robin Humphry-Baker,Shaik M. Zakeeruddin,Peter Pechy,Purificación Vázquez,Emilio Palomares,Michael Grätzel,Mohammad Khaja Nazeeruddin,Tomás Torres,Tomás Torres +10 more
TL;DR: In this paper, an unsymmetrical zinc phthalocyanine (TT9) sensitizer that consists of three tert-butyl and two carboxylic acid groups that act as "push" and "pull" respectively was designed and developed.
Journal ArticleDOI
Electronic structures and absorption spectra of linkage isomers of trithiocyanato (4,4',4' '-tricarboxy-2,2':6,2' '-terpyridine) ruthenium(II) complexes: a DFT study.
Sutapa Ghosh,and G. Krishna Chaitanya,Kotamarthi Bhanuprakash,Md. K. Nazeeruddin and,Michael Grätzel,P. Yella Reddy +5 more
TL;DR: The geometry of black dye and its isomers and the bonding in these isomers using NBO methods are calculated by DFT and scalar relativistic zero-order regular approximations are carried out to simulate the absorption spectra.
Journal ArticleDOI
One-step mechanochemical incorporation of an insoluble cesium additive for high performance planar heterojunction solar cells
Daniel Prochowicz,Daniel Prochowicz,Pankaj Yadav,Pankaj Yadav,Michael Saliba,Michael Saliba,Dominik J. Kubicki,Mohammad Mahdi Tavakoli,Mohammad Mahdi Tavakoli,Shaik M. Zakeeruddin,Janusz Lewiński,Janusz Lewiński,Lyndon Emsley,Michael Grätzel +13 more
TL;DR: In this paper, insoluble CsCl, as a new source of cesium cation, can be integrated into a multiple-cation perovskite material by a one-step method involving grinding of the precursors.
