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…
