Organic-Inorganic Halide Perovskites: Perspectives for Silicon-Based Tandem Solar Cells

Christophe Ballif, Jun Ho Yum, Soo-Jin Moon, Stefaan De Wolf, Franz-Josef Haug, Jakub Holovsky, Björn Niesen, Martin Ledinsky

We investigate the efficiency potential of organic-inorganic halide perovskite/crystalline silicon tandem solar cells, a new class of photovoltaic devices targeting long-term cost reductions by ultrahigh conversion efficiencies. Methyl ammonium lead triiod ...

Organometallic Halide Perovskites: Sharp Optical Absorption Edge and Its Relation to Photovoltaic Performance

Christophe Ballif, Jun Ho Yum, Soo-Jin Moon, Stefaan De Wolf, Franz-Josef Haug, Jakub Holovsky, Björn Niesen, Martin Ledinsky

Solar cells based on organometallic halide perovskite absorber layers are emerging as a high-performance photovoltaic technology. Using highly sensitive photothermal deflection and photocurrent spectroscopy, we measure the absorption spectrum of CH3NH3PbI3 ...

Thin Film Metal Nanocluster Light-Emitting Devices

Björn Niesen

Light-emitting devices that utilize thin films of metal nanoclusters as quantum emitters are presented. Implementing Ag as well as Au nanoclusters, the versatility of the approach is demonstrated, and it is shown that the electroluminescence measured from ...

Self-Patterned Nanoparticle Layers for Vertical Interconnects: Application in Tandem Solar Cells

Christophe Ballif, Aïcha Hessler-Wyser, Fanny Sculati-Meillaud, Nicolas Blondiaux, Raphaël Pugin, Franz-Josef Haug, Mathieu Gérard Boccard, Michael Elias Stückelberger, Emmanuel Scolan, Björn Niesen

We demonstrate self-patterned insulating nanoparticle layers to define local electrical interconnects in thin-film electronic devices. We show this with thin-film silicon tandem solar cells, where we introduce between the two component cells a solution-pro ...
