Michael Saliba,Taisuke Matsui,Ji-Youn Seo,Konrad Domanski,Juan-Pablo Correa-Baena,Mohammad Khaja Nazeeruddin,Shaik M. Zakeeruddin,Wolfgang Tress,Antonio Abate,Anders Hagfeldt,Michael Grätzel +10 more
TL;DR: In this paper, the triple cation perovskite photovoltaics with inorganic cesium were shown to be thermally more stable, contain less phase impurities and are less sensitive to processing conditions.
Journal ArticleDOI
Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance
Michael Saliba,Taisuke Matsui,Taisuke Matsui,Konrad Domanski,Ji-Youn Seo,Amita Ummadisingu,Shaik M. Zakeeruddin,Juan-Pablo Correa-Baena,Wolfgang Tress,Antonio Abate,Anders Hagfeldt,Michael Grätzel +11 more
TL;DR: This work shows that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a “cation cascade” to create perovskite materials with excellent material properties and achieved stabilized efficiencies of up to 21.6% on small areas.
Journal ArticleDOI
Efficient luminescent solar cells based on tailored mixed-cation perovskites
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
Promises and challenges of perovskite solar cells
Juan-Pablo Correa-Baena,Juan-Pablo Correa-Baena,Michael Saliba,Tonio Buonassisi,Michael Grätzel,Antonio Abate,Wolfgang Tress,Anders Hagfeldt +7 more
TL;DR: Because photocurrents are near the theoretical maximum, the focus is on efforts to increase open-circuit voltage by means of improving charge-selective contacts and charge carrier lifetimes in perovskites via processes such as ion tailoring.
Journal ArticleDOI
Understanding the rate-dependent J–V hysteresis, slow time component, and aging in CH3NH3PbI3 perovskite solar cells: the role of a compensated electric field
Wolfgang Tress,Nevena Marinova,Thomas Moehl,Shaik M. Zakeeruddin,Mohammad Khaja Nazeeruddin,Michael Grätzel +5 more
TL;DR: In this paper, the rate-dependent hysteresis seen in current-voltage scans of CH3NH3PbI3 perovskite solar cells is related to a slow field-induced process that tends to cancel the electric field in the device at each applied bias voltage.
