Mitigating Plasmonic Absorption Losses at Rear Electrodes in High‐Efficiency Silicon Solar Cells Using Dopant‐Free Contact Stacks

Christophe Ballif, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Stefaan De Wolf, Julie Amandine Dreon, Fan Fu, Sihua Zhong

Although charge‐carrier selectivity in conventional crystalline silicon (c‐Si) solar cells is usually realized by doping Si, the presence of dopants imposes inherent performance limitations due to parasitic absorption and carrier recombination. The develop ...

Perovskite/Perovskite/Silicon Monolithic Triple-Junction Solar Cells with a Fully Textured Design

Christophe Ballif, Jérémie Werner, Quentin Thomas Jeangros, Florent Sahli, Arnaud Walter, Sylvain Nicolay, Björn Niesen, Fan Fu

High efficiency triple-junction solar cells are currently made of III−V semiconductors using expensive deposition methods. Perovskite/perovskite/silicon monolithic triple-junction solar cells could be a lower-cost alternative as no epitaxial growth is requ ...

Impact of interlayer application on band bending for improved electron extraction for efficient flexible perovskite mini-modules

Romain Carron, Roland Widmer, Fan Fu

The development of highly efficient lightweight flexible perovskite solar cells (PSCs) opens the way to high-throughput roll-to-roll manufacturing processes and new applications such as building integration and mobile products. Flexible PSCs are generally ...

Tailored lead iodide growth for efficient flexible perovskite solar cells and thin-film tandem devices

Romain Carron, Fan Fu

Flexible perovskite solar cells (PSCs) hold great promise for the low-cost roll-to-roll production of lightweight single- and multijunction photovoltaic devices. Among the different deposition methods used for the perovskite absorber, the two-step hybrid v ...

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

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 ...

High-Efficiency Polycrystalline Thin Film Tandem Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Antonio Abate, Fan Fu

A promising way to enhance the efficiency of CIGS solar cells is by combining them with perovskite solar cells in tandem devices. However, so far, such tandem devices had limited efficiency due to challenges in developing NIR-transparent perovskite top cel ...
