Lateral ion migration accelerates degradation in halide perovskite devices

Christophe Ballif, Quentin Thomas Jeangros, Kerem Artuk, Christian Michael Wolff, Xin Yu Chin, Daniel Anthony Jacobs

The migration of mobile ions has long been considered a source of performance degradation in devices based on halide perovskites, but details regarding the mechanisms and extent of this problem remain scarce. Here we report the finding that differences in ...

Synergetic substrate and additive engineering for over 30%-efficient perovskite-Si tandem solar cells

Christophe Ballif, Mathieu Gérard Boccard, Quentin Thomas Jeangros, Mounir Driss Mensi, Christian Michael Wolff, Kerem Artuk, Deniz Türkay, Daniel Anthony Jacobs, Xin Yu Chin

Perovskite-silicon (Si) tandem solar cells are the most prominent contenders to succeed single-junction Si cells that dominate the market today. Yet, to justify the added cost of inserting a perovskite cell on top of Si, these devices should first exhibit ...

Below the Urbach Edge: Solar Cell Loss Analysis Based on Full External Quantum Efficiency Spectra

Stefaan De Wolf, Jakub Holovsky, Xin Yu Chin

We suggest a new solar cell loss analysis using theexternal quantumefficiency (EQE) measured with sufficiently high sensitivity to alsoaccount for defects. Unlike common radiative-limit methods, wherethe impact of deep defects is ignored by exponential ext ...

High-Performance Flexible All-Perovskite Tandem Solar Cells with Reduced V-OC-Deficit in Wide-Bandgap Subcell

Quentin Thomas Jeangros, Fan Fu, Xin Yu Chin

Among various types of perovskite-based tandem solar cells (TSCs), all-perovskite TSCs are of particular attractiveness for building- and vehicle-integrated photovoltaics, or space energy areas as they can be fabricated on flexible and lightweight substrat ...

Correlating light-induced deep defects and phase segregation in mixed-halide perovskites

Quentin Thomas Jeangros, Jakub Holovsky, Christian Michael Wolff, Peter Joseph Fiala, Xin Yu Chin

Mixed-halide perovskites are highly promising materials for tandem solar cells. The phenomenon of phase segregation, however hinders their application. Here, we combine Fourier-Transform photocurrent spectroscopy with photoluminescence and current density- ...

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

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

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 ...
