Journal ArticleDOI
Effect of Annealing Temperature on Film Morphology of Organic–Inorganic Hybrid Pervoskite Solid‐State Solar Cells
Amalie Dualeh,Nicolas Tétreault,Thomas Moehl,Peng Gao,Mohammad Khaja Nazeeruddin,Michael Grätzel +5 more
TL;DR: The role of the temperature used in the annealing process required to convert the as deposited solution into the perovskite material is investigated in this paper, where it is found that the conversion requires sufficiently high temperatures to ensure the vaporization of solvent and the crystallization of the material.
Journal ArticleDOI
Inorganic hole conductor-based lead halide perovskite solar cells with 12.4% conversion efficiency
Peng Qin,Soichiro Tanaka,Seigo Ito,Nicolas Tétreault,Kyohei Manabe,Hitoshi Nishino,Mohammad Khaja Nazeeruddin,Michael Grätzel +7 more
TL;DR: This work demonstrates the application of an effective and cheap inorganic p-type hole-transporting material, copper thiocyanate, on lead halide perovskite-based devices and opens the door for integration of a class of abundant and inexpensive material for photovoltaic application.
Journal ArticleDOI
Passivating surface states on water splitting hematite photoanodes with alumina overlayers
TL;DR: In this article, an ultra-thin coating of Al2O3 was applied on the surface of high-performance hematite to reduce the overpotential of the material and increase the photocurrent.
Journal ArticleDOI
Impedance Spectroscopic Analysis of Lead Iodide Perovskite-Sensitized Solid-State Solar Cells
Amalie Dualeh,Thomas Moehl,Nicolas Tétreault,Joël Teuscher,Peng Gao,Mohammad Khaja Nazeeruddin,Michael Grätzel +6 more
TL;DR: The features in the IS responses that are attributed to the ionic and electronic transport properties of the perovskite material and manifest as a slow response at low frequency and an additional RC element at intermediate frequency are explored.
Journal ArticleDOI
Efficient Near-Infrared-Transparent Perovskite Solar Cells Enabling Direct Comparison of 4-Terminal and Monolithic Perovskite/Silicon Tandem Cells
Jérémie Werner,Loris Barraud,Arnaud Walter,Matthias Bräuninger,Florent Sahli,Davide Sacchetto,Nicolas Tétreault,Bertrand Paviet-Salomon,Soo-Jin Moon,Christophe Allebe,Matthieu Despeisse,Sylvain Nicolay,Stefaan De Wolf,Bjoern Niesen,Christophe Ballif +14 more
TL;DR: In this article, a 1 cm2 near-infrared transparent perovskite solar cell with 14.5% steady-state efficiency was presented, as compared to 16.4% on 0.25 cm2.
