Pizza Oven Processing of Organohalide Perovskites (POPOP): A Simple, Versatile and Efficient Vapor Deposition Method

Christophe Ballif, Cédric Bucher, Christian Michael Wolff, Austin George Kuba, Deniz Türkay, Kerem Artuk, Quentin Jean-Marie Armand Guesnay

Hybrid vapor deposition is one of the most appealing processes for perovskite photovoltaics fabrication, thanks to its versatile nature. By using sequentially different vapor deposition processes tailored to the inorganic and organic perovskite precursors' ...

Vapor Deposition of Perovskite Solar Cells

Quentin Jean-Marie Armand Guesnay

Thanks to the continuous improvement of crystalline silicon (c-Si) solar cells, largely dominating the market, photovoltaic electricity is nowadays the cheapest source of energy on the market. Yet, solar energy is far from being completely harvested, as t ...

Interface passivation for 31.25%-efficient perovskite/silicon tandem solar cells

Christophe Ballif, Quentin Thomas Jeangros, Mounir Driss Mensi, Christian Michael Wolff, Daniel Anthony Jacobs, Deniz Türkay, Kerem Artuk, Mathieu Gérard Boccard, Peter Joseph Fiala, Quentin Jean-Marie Armand Guesnay

Silicon solar cells are approaching their theoretical efficiency limit of 29%. This limitation can be exceeded with advanced device architectures, where two or more solar cells are stacked to improve the harvesting of solar energy. In this work, we devise ...

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 ...

Vapor Transport Deposition of Methylammonium Iodide for Perovskite Solar Cells

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

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 ...
