A High-Performance Quasi-1D MoS Nanoribbon Photodetector
Ganesh Ghimire, Rajesh Kumar Ulaganathan, Agnes Tempez +11
Molybdenum disulfide (MoS) nanoribbons have attracted increased interest due to their properties which can be tailored by tuning their dimensions. Herein, we demonstrate the gr…
Combining experiments on luminescent centres in hexagonal boron nitride with the polaron model and ab initio methods towards the identification of their microscopic origin
Moritz Fischer, Ali Sajid, Jake Iles-Smith +10
The two-dimensional material hexagonal boron nitride (hBN) hosts luminescent centres with emission energies of 2 eV which exhibit pronounced phonon sidebands. We investigate the mi…
A Facile Strategy for the Growth of High-Quality Tungsten Disulfide Crystals Mediated by Oxygen-Deficient Oxide Precursors
Denys I. Miakota1, Raymond R. Unocic2, Fabian Bertoldo3 +5
Chemical vapor deposition (CVD) has been established as a versatile route for the large-scale synthesis of transition metal dichalcogenides, such as tungsten disulfide (WS2). Yet,…
Gettering in polySi/SiOx passivating contacts enables Si-based tandem solar cells with high thermal and contamination resilience
Alireza Assar, Filipe Martinho, Jes Larsen +12
Multijunction solar cells in a tandem configuration could further lower the costs of electricity if crystalline Si (c-Si) is used as bottom cell. However, for direct monolithic int…
Non-destructive determination of phase, size, and strain of individual grains in polycrystalline photovoltaic materials
Mariana Mar Lucas, Tiago Ramos, Peter S. Jørgensen +5
We demonstrate a non-destructive approach to provide structural properties on the grain level for the absorber layer of kesterite solar cells. Kesterite solar cells are notoriously…
Monolithic thin-film chalcogenide-silicon tandem solar cells enabled by a diffusion barrier
Alireza Hajijafarassar, Filipe Martinho, Fredrik Stulen +12
Following the recent success of monolithically integrated Perovskite/Si tandem solar cells, great interest has been raised in searching for alternative wide bandgap top-cell materi…
Persistent double layer formation in kesterite solar cells: a critical review
Filipe Martinho, Simon Lopez-Marino, Moises Espíndola-Rodríguez +11
In kesterite CZTSSe solar cell research, an asymmetric crystallization profile is often obtained after annealing, resulting in a bilayered or double-layered absorber. So far, only…
Nitride-based interfacial layers for monolithic tandem integration of new solar energy materials on Si: The case of CZTS
Filipe Martinho, Alireza Hajijafarassar, Simón Lopez-Marino +11
The monolithic tandem integration of third-generation solar energy materials on silicon holds great promise for photoelectrochemistry and photovoltaics. However, this can be challe…
