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…
Challenges for the future of tandem photovoltaics on the path to terawatt levels: A technology review
Filipe Martinho
As the photovoltaic sector approaches 1 TW in cumulative installed capacity, we provide an overview of the current challenges to achieve further technological improvements. On the…
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…
