Journal ArticleDOI
Lead Iodide Perovskite Sensitized All-Solid-State Submicron Thin Film Mesoscopic Solar Cell with Efficiency Exceeding 9%
Hui-Seon Kim,Chang-Ryul Lee,Jeong-Hyeok Im,Ki Beom Lee,Thomas Moehl,Arianna Marchioro,Soo-Jin Moon,Robin Humphry-Baker,Jun-Ho Yum,Jacques-E. Moser,Michael Grätzel,Nam-Gyu Park +11 more
TL;DR: The use of a solid hole conductor dramatically improved the device stability compared to (CH3NH3)PbI3 -sensitized liquid junction cells.
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.
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
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.
