Vapor Transport Deposition of Methylammonium Iodide for Perovskite Solar Cells

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Cédric Bucher, Aymeric Michel Schafflützel, Björn Niesen, Léo Duchêne, Quentin Jean-Marie Armand Guesnay, Niccolo Salsi, Nathanaël Miaz

Vapor-based processes are promising options to deposit metal halide perovskite solar cells in an industrial environment due to their ability to deposit uniform layers over large areas in a controlled environment without resorting to the use of (possibly to ...

Vapor deposition of metal halide perovskite thin films: Process control strategies to shape layer properties

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Quentin Jean-Marie Armand Guesnay

Vapor-based processes are particularly promising to deposit the perovskite thin film absorber of solar cells. These deposition methods are up-scalable, involve a controlled solvent-free environment, have the ability to conformally coat rough substrates, in ...

Ammonia-assisted vapour transport deposition of formamidinium salts for perovskite thin films

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Léo Duchêne, Quentin Jean-Marie Armand Guesnay, Niccolo Salsi

Formamidinium (FA) cations commonly used in perovskite semiconductors tend to form sym-triazine when sublimed in vacuum, a process that hampers the deposition process. Here we find that ammonia, when used as a carrier gas for formamidinium halides transpor ...
