Role of the Selective Contacts in the Performance of Lead Halide Perovskite Solar Cells.
Emilio J. Juarez-Perez,Michael Wuβler,Michael Wuβler,Francisco Fabregat-Santiago,K. Lakus-Wollny,Eric Mankel,Thomas Mayer,Wolfram Jaegermann,Iván Mora-Seró +8 more
TL;DR: It has been determined that the recombination rate is mainly governed by the selective contacts, which has important implication for the future optimization of perovskite solar cells.
Journal ArticleDOI
Nanostructured SnO2–ZnO Heterojunction Photocatalysts Showing Enhanced Photocatalytic Activity for the Degradation of Organic Dyes
M. T. Uddin,Yohann Nicolas,Céline Olivier,Thierry Toupance,Laurent Servant,Mathis M. Müller,Hans-Joachim Kleebe,Jürgen Ziegler,Wolfram Jaegermann +8 more
TL;DR: The heterostructure SnO(2)-ZnO photocatalyst showed much higher photocatalytic activities for the degradation of methylene blue than those of individual Sno(2) and ZnO nanomaterials and could be easily recycled several times opening new avenues for potential industrial applications.
Journal ArticleDOI
Fundamental degradation mechanisms of layered oxide Li-ion battery cathode materials: Methodology, insights and novel approaches
René Hausbrand,Gennady Cherkashinin,Helmut Ehrenberg,Melanie Gröting,Karsten Albe,Christian Hess,Wolfram Jaegermann +6 more
TL;DR: In this article, the atomistic aspects of degradation of layered LiMO2 (M = Ni, Co, Mn) oxide Li-ion battery cathode materials, aiming to shed light on the fundamental degradation mechanisms especially inside active cathode material and at their interfaces.
Journal ArticleDOI
Photoelectrochemistry of Highly Quantum Efficient Single‐Crystalline n ‐ FeS2 (Pyrite)
TL;DR: In this paper, the formation and the dynamics of a thin oxidation layer that forms at the surface of the electrode in the presence of an acid electrolyte were studied using light reflection techniques and ESCA.
Journal ArticleDOI
Hybrid Perovskite/Perovskite Heterojunction Solar Cells
Yinghong Hu,Johannes Schlipf,Michael Wussler,Michiel L. Petrus,Wolfram Jaegermann,Thomas Bein,Peter Müller-Buschbaum,Pablo Docampo +7 more
TL;DR: The results show that the self-assembly of the LPK layer on top of an intact MAPI layer is accompanied by a reorganization of the perovskite interface, which leads to an enhancement of the open-circuit voltage and power conversion efficiency due to reduced recombination losses, as well as improved moisture stability in the resulting photovoltaic devices.
