High-κ Wide-Gap Layered Dielectric for Two-Dimensional van der Waals Heterostructures
Andras Kis, Edoardo Lopriore, Asmund Kjellegaard Ottesen, Gabriele Pasquale
van der Waals heterostructures of two-dimensional materials have unveiled frontiers in condensed matter physics, unlocking unexplored possibilities in electronic and photonic device applications. However, the investigation of wide-gap, high-kappa layered d ...
2024Improving the photoelectrocatalytic efficiency of CuWO4 through molybdenum for tungsten substitution and coupling with BiVO4
A systematic investigation on the photoelectrocatalytic (PEC) performance of a series of CuW1-xMoxO4 materials with different Mo for W substitution (x = 0-0.8), successfully synthesized as single, transparent photoactive layers, allowed us to identify copp ...
Royal Soc Chemistry2024High-Quality Data Enabling Universality of Band Gap Descriptor and Discovery of Photovoltaic Perovskites
Alfredo Pasquarello, Haiyuan Wang, Wei Chen
Extensive machine-learning-assisted research has been dedicated to predicting band gaps for perovskites, driven by their immense potential in photovoltaics. Yet, the effectiveness is often hampered by the lack of high-quality band gap data sets, particular ...
Amer Chemical Soc2024A comprehensive physical model for the sensitivity of silicon heterojunction photovoltaic modules to water ingress
Christophe Ballif, Alessandro Francesco Aldo Virtuani, Olatz Arriaga Arruti, Luca Gnocchi
Silicon heterojunction (SHJ)-solar modules-when encapsulated with ethylene vinyl acetate (EVA)-are known to be extremely sensitive to water ingress. The reason for this is, however, not clear. Here, we explain the root causes of this degradation mechanism ...
Cambridge2024Enhanced performance of perovskite solar cell via up-conversion YLiF4:Yb, Er nanoparticles
Mounir Driss Mensi, Masaud Hassan S Almalki, Anwar Qasem M Alanazi
We report a simple and effective method for producing lanthanide ion-doped lithium-fluoride-based nanocrystals (YLiF4). We utilized those nanoparticles for up-conversion in fabricated perovskite solar cells. The obtained results shows that the up-conversio ...
Elsevier2024Aptamer Renaissance for Neurochemical Biosensing
Unraveling the complexities of brain function, which is crucial for advancing human health, remains a grand challenge. This endeavor demands precise monitoring of small molecules such as neurotransmitters, the chemical messengers in the brain. In this Pers ...
2024Semiconductor-based device architectures in multimaterial fibers
William Nicolas Duncan Esposito
Semiconductor materials have given rise to today's digital technology and consumer electronics. Widespread adoption is closely linked to the ability to process and integrate them in devices at scale. Where flexibility and large surfaces are required, such ...
