Efficient Monolithic Perovskite/Silicon Tandem Solar Cell with Cell Area >1 cm

Christophe Ballif, Arnaud Walter, Stefaan De Wolf, Björn Niesen, Jérémie Werner, Johannes Peter Seif, Luc Fesquet, Ching-Hsun Weng

Monolithic perovskite/crystalline silicon tandem solar cells hold great promise for further performance improvement of well-established silicon photovoltaics; however, monolithic tandem integration is challenging, evidenced by the modest performances and s ...

Silicon-organic hybrid (SOH) devices and their use in comb-based communication systems

Tobias Kippenberg, Victor Brasch, Tobias Herr

Advanced wavelength-division multiplexing (WDM) requires both efficient multi-wavelength light sources to generate optical carriers and highly scalable photonic-electronic interfaces to encode data on these carriers. In this paper, we give an overview on o ...

Lanthanides in Solar Energy Conversion

Jean-Claude Bünzli, Anne-Sophie Chauvin

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...
