Two birds with one stone: dual grain-boundary and interface passivation enables >22% efficient inverted methylammonium-free perovskite solar cells
Saba Gharibzadeh,Paul Fassl,Ihteaz M. Hossain,Pascal Rohrbeck,Markus Frericks,Moritz Schmidt,Motiur Rahman Khan,Tobias Abzieher,Bahram Abdollahi Nejand,Fabian Schackmar,Osbel Almora,Thomas Feeney,Roja Singh,Dirk Fuchs,Uli Lemmer,Jan P. Hofmann,Stefan A. L. Weber,Ulrich W. Paetzold +17 more
TL;DR: In this article, a dual passivation strategy using the long chain alkylammonium salt phenethylamium chloride (PEACl) both as an additive and for surface treatment to simultaneously passivate the grain boundaries and the perovskite/C60 interface was introduced.
Journal ArticleDOI
Coated and Printed Perovskites for Photovoltaic Applications.
Ian A. Howard,Tobias Abzieher,Ihteaz M. Hossain,Helge Eggers,Fabian Schackmar,Simon Ternes,Bryce S. Richards,Uli Lemmer,Ulrich W. Paetzold +8 more
TL;DR: The opportunities to fully close the shrinking gap to record spin-coated solar cells and to scale these efficiencies to large areas are highlighted.
Journal ArticleDOI
2D/3D Heterostructure for Semitransparent Perovskite Solar Cells with Engineered Bandgap Enables Efficiencies Exceeding 25% in Four‐Terminal Tandems with Silicon and CIGS

TL;DR: In this paper, a 2D/3D perovskite heterostructure passivation is employed for double-cation wide-bandgap PSCs with engineered bandgap, which results in improved stabilized PCEs and a strong enhancement in open-circuit voltages of around 45 mV compared to reference devices for all investigated bandgaps.

TL;DR: In this paper, a Ruddlesden-Popper "quasi-2D" perovskite phase is formed on the surface of the 3D perovsite that passivates the surface defects and significantly improves the device performance.
Journal ArticleDOI
Spectral Dependence of Degradation under Ultraviolet Light in Perovskite Solar Cells
Amjad Farooq,Ihteaz M. Hossain,Somayeh Moghadamzadeh,Jonas A. Schwenzer,Tobias Abzieher,Bryce S. Richards,Efthymios Klampaftis,Ulrich W. Paetzold +7 more
TL;DR: It is demonstrated that photodegradation is apparent for high, as well as for low illumination intensities of UV-B light, but not for illumination with UV-A wavelengths, and that degradation of PSCs is preventable by using UV-filtering or luminescent downshifting layers.
