22% Efficient Dopant-free Interdigitated Back Contact Silicon Solar Cells

Christophe Ballif, Matthieu Despeisse, Mathieu Gérard Boccard, Bertrand Yves Paul Paviet-Salomon, Sihua Zhong

In this study, we present dopant-free back contact heterojunction silicon solar cells employing MoOx and MgFx based stacks as hole-and electron-selective contacts deposited using a thermal evaporation process at low temperature. Only two masking steps and ...

Reactively Sputtered Nano-Structured Multilayer Coatings on Architectural Glazing for Active Solar Energy Façades

Stefan Mertin

Improving the aesthetic of solar thermal collectors would grant architects a huge potential for a perfect integration of solar panels into building façades: this can be achieved by coloured interference coatings on the cover glass. These coatings also open ...

Record Infrared Internal Quantum Efficiency in Silicon Heterojunction Solar Cells With Dielectric/Metal Rear Reflectors

Christophe Ballif, Stefaan De Wolf, Antoine Descoeudres

Inserting a dielectric between the absorber and rear metal electrode of a solar cell increases rear internal reflectance by both limiting the transmission cone and suppressing the plasmonic absorption of light arriving outside of the cone. We fabricate rea ...

Universal Dynamics of Kerr-Frequency Comb Formation in Microresonators

Tobias Kippenberg, Tobias Herr, Emanuel Gavartin

We experimentally investigate the initial dynamics of Kerr-frequency comb formation in crystalline MgF2 and planar Si3N4 microresonator and present a universal, platform independent condition for low phase noise performance. ...
