Journal ArticleDOI
Large guanidinium cation mixed with methylammonium in lead iodide perovskites for 19% efficient solar cells
Alexander D. Jodlowski,Alexander D. Jodlowski,Cristina Roldán-Carmona,Giulia Grancini,Manuel Salado,Maryline Ralaiarisoa,Maryline Ralaiarisoa,Shahzada Ahmad,Norbert Koch,Norbert Koch,Luis Camacho,Gustavo de Miguel,Mohammad Khaja Nazeeruddin +12 more
TL;DR: In this paper, a large organic cation, guanidinium, was incorporated into the MAPbI3 crystal structure, which achieved improved material stability after the incorporation of the organic component.
Journal ArticleDOI
Influence of Charge Transport Layers on Open-Circuit Voltage and Hysteresis in Perovskite Solar Cells
Sandheep Ravishankar,Saba Gharibzadeh,Saba Gharibzadeh,Cristina Roldán-Carmona,Giulia Grancini,Yonghui Lee,Maryline Ralaiarisoa,Maryline Ralaiarisoa,Abdullah M. Asiri,Nobert Koch,Nobert Koch,Juan Bisquert,Mohammad Khaja Nazeeruddin +12 more
TL;DR: In this article, the authors directly target the interplay between the charge-transporting layers and open-circuit potential (VOC) in the operation mechanism of CH 3 NH 3 PbI 3 solar cells.
Journal ArticleDOI
Impact of White Light Illumination on the Electronic and Chemical Structures of Mixed Halide and Single Crystal Perovskites
Fengshuo Zu,Patrick Amsalem,Ingo Salzmann,Rongbin Wang,Rongbin Wang,Maryline Ralaiarisoa,Stefan Kowarik,Steffen Duhm,Norbert Koch,Norbert Koch +9 more
TL;DR: In this article, the effect of white light illumination on the electronic and chemical properties of mixed halide perovskite (CH3NH3PbI3−xClx) thin films and single crystals using photoelectron and absorption spectroscopy was investigated.
Journal ArticleDOI
Perfluorinated Self-Assembled Monolayers Enhance the Stability and Efficiency of Inverted Perovskite Solar Cells
Christian M. Wolff,Laura Canil,Carolin Rehermann,Nguyen Ngoc Linh,Fengshuo Zu,Maryline Ralaiarisoa,Pietro Caprioglio,Lukas Fiedler,Martin Stolterfoht,Sergio Kogikoski,Ilko Bald,Norbert Koch,Eva L. Unger,Thomas Dittrich,Antonio Abate,Dieter Neher +15 more
TL;DR: This work demonstrates the application of a simple solution-processed perfluorinated self-assembled monolayer (p-SAM) that not only passivates the perovskite surface but also drastically improves the stability of the pervskite absorber and in turn the solar cell under elevated temperature or humid conditions.
Journal ArticleDOI
Surface State Density Determines the Energy Level Alignment at Hybrid Perovskite/Electron Acceptors Interfaces.
Fengshuo Zu,Patrick Amsalem,Maryline Ralaiarisoa,Thorsten Schultz,Raphael Schlesinger,Norbert Koch,Norbert Koch +6 more
TL;DR: It is demonstrated that donor-like surface states stemming from reduced lead directly impact the energy level alignment at perovskite and molecular electron acceptor layer interfaces using photoelectron spectroscopy.
