Colloidal-ALD-Grown Core/Shell CdSe/CdS Nanoplatelets as Seen by DNP Enhanced PASS-PIETA NMR Spectroscopy

David Lyndon Emsley, Laura Piveteau, Brennan James Walder

Ligand exchange and CdS shell growth onto colloidal CdSe nanoplatelets (NPLs) using colloidal atomic layer deposition (c-ALD) were investigated by solid-state nuclear magnetic resonance (NMR) experiments, in particular, dynamic nuclear polarization (DNP) e ...

Hole-Selective Front Contact Stack Enabling 24.1%-Efficient Silicon Heterojunction Solar Cells

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Laurie-Lou Senaud, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Jan Haschke, Luca Massimiliano Antognini, Jean Cattin, Julie Amandine Dreon, Vincent Philippe Paratte, Wenjie Lin, Minh Truong

The window-layer stack limits the efficiency of both-side-contacted silicon heterojunction solar cells. We discuss here the combination of several modifications to this stack to improve its optoelectronic performance. These include the introduction of a na ...

Multiple morphologies and functionality of nanowires made from earth-abundant zinc phosphide

Anna Fontcuberta i Morral, Elias Zsolt Stutz, Jean-Baptiste Leran, Mahdi Zamani, Simon Robert Escobar Steinvall, Nicolas Tappy, Rajrupa Paul, Reza Zamani

Semiconductors made of earth-abundant elements, such as zinc phosphide, have the potential to substitute less abundant, highly functional compound semiconductors such as InAs or InP. Compound semiconductors in the form of nanowires could revolutionise appl ...

Probing Alloy Formation Using Different Excitonic Species: The Particular Case of InGaN

Nicolas Grandjean, Raphaël Butté, Gordon Jens Callsen

Since the early 1960s, alloys are commonly grouped into two classes that feature either bound states in the band gap (I) or additional, nondiscrete band states (II). Consequently, one can observe either excitons bound to isoelectronic impurities or the typ ...

A multi-technique approach to study the microstructural properties of tin-based transparent conductive oxides

Federica Landucci

Transparent conductive oxides (TCOs) are semiconductor-like materials that exhibit high electrical conductivity and high optical transparency combined. They are adopted in various applications ranging from gas sensors, to electrochromic windows, to photovo ...

Zr-doped indium oxide electrodes: Annealing and thickness effects on microstructure and carrier transport

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Monica Morales Masis, Oscar Esteban Rucavado Leandro, Federica Landucci

Zr-doped indium oxide (In2O3:Zr) has been shown to satisfy the requirements of low resistance, wide band gap, and high infrared transmittance for application as a front contact in broadband solar cells. However, the reduction of indium usage in front of tr ...

Elucidating the role of the InGaN UL in the efficiency of InGaN based light-emitting diodes

Camille Haller

Blue III-nitride light-emitting diodes (LEDs) are widely used nowadays in solid-state lighting, as white light can be produced by combining yellow phosphors and blue LEDs. This technology has the advantage to have a higher luminous efficiency than incandes ...
