Fully textured monolithic perovskite/silicon tandem solar cells with 25.2% power conversion efficiency

Christophe Ballif, Quentin Thomas Jeangros, Davide Sacchetto, Bertrand Yves Paul Paviet-Salomon, Florent Sahli, Gianluca Cattaneo, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Björn Niesen, Loris Barraud, Laura Ding, Jérémie Werner, Matthias Wolfgang Bräuninger, Raphaël Monnard

Tandem devices combining perovskite and silicon solar cells are promising candidates to achieve power conversion efficiencies above 30% at reasonable costs. State-of-the-art monolithic two-terminal perovskite/silicon tandem devices have so far featured sil ...

Complex Refractive Indices of Cesium–Formamidinium-Based Mixed-Halide Perovskites with Optical Band Gaps from 1.5 to 1.8 eV

Christophe Ballif, Quentin Thomas Jeangros, Gabriel Christmann, Florent Sahli, Arnaud Walter, Sylvain Nicolay, Björn Niesen, Jérémie Werner, Gizem Nogay, Philipp Friedrich Hermann Löper, Matthias Wolfgang Bräuninger, Chien-Jen Yang, Peter Joseph Fiala

Cesium-formamidinium-based mixed-halide perovskite materials with optical band gaps ranging from 1.5 to 1.8 eV are investigated by variable-angle spectroscopic ellipsometry. The determined complex refractive indices are shown to depend on the fabrication p ...

Hybrid sequential deposition process for fully textured perovskite/silicon tandem solar cells

Christophe Ballif, Quentin Thomas Jeangros, Davide Sacchetto, Bertrand Yves Paul Paviet-Salomon, Florent Sahli, Arnaud Walter, Gianluca Cattaneo, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Björn Niesen, Monica Morales Masis, Soo-Jin Moon, Loris Barraud, Laura Ding, Jérémie Werner, Gizem Nogay, Matthias Wolfgang Bräuninger, Oscar Esteban Rucavado Leandro, Raphaël Monnard, Fan Fu, Chien-Jen Yang, Peter Joseph Fiala

Tandem solar cells that feature a high-bandgap perovskite cell on top of a lower bandgap silicon cell have the potential to reach efficiencies > 30%. Here, we present a versatile hybrid deposition method that yields conformal perovskite cells directly on t ...

Spectrally resolved nonlinearity and temperature dependence of perovskite solar cells

Christophe Ballif, Florent Sahli, Björn Niesen, Jérémie Werner, Matthias Wolfgang Bräuninger

An accurate electrical device characterization of hybrid organic-inorganic halide perovskite solar cells (PSCs) is an important prerequisite for further improvement and industrial transfer of this promising photovoltaic technology. In this work, we study t ...
