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…
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…
Water adsorption enhances electrical conductivity in transparent p-type CuI
Andrea Crovetto, Hannes Hempel, Marin Rusu +4
CuI has been recently rediscovered as a p-type transparent conductor with a high figure of merit. Even though many metal iodides are hygroscopic, the effect of moisture on the elec…
A general approach for the synthesis of two-dimensional binary compounds
Abhay Shivayogimath, Joachim Dahl Thomsen, David M. A. Mackenzie +7
Only a few of the vast range of potential two-dimensional materials have been isolated or synthesised to date. Typically, 2D materials are discovered by mechanically exfoliating na…
Measuring complete band diagrams of non-ideal heterointerfaces by combining ellipsometry and photoemission spectroscopy
Andrea Crovetto
In this work, we show that spectroscopic ellipsometry can be combined with photoemission spectroscopy to obtain complete interface band diagrams of non-ideal semiconductor heteroin…
