Ultraviolet radiation impact on the efficiency of commercial crystalline silicon-based photovoltaics: A theoretical thermal-electrical study in realistic device architectures
George Perrakis, Anna C. Tasolamprou, George Kenanakis +3
We investigate and evaluate the contribution of the ultraviolet radiation spectrum on the temperature and efficiency of commercial crystalline silicon-based photovoltaics (PVs) tha…
Fabrication and characterization of Fused Deposition Modeling 3D printed mm-scaled metasurface units
Anna C. Tasolamprou, Despoina Mentzaki, Zacharias Viskadourakis +3
We present a cost-effective, eco-friendly and accessible method for fabricating three-dimensional, ultralight and flexible millimeter-scale metasurfaces using a household 3D printe…
Passive radiative cooling impact on commercial crystalline silicon-based photovoltaics
George Perrakis, Anna C. Tasolamprou, George Kenanakis +3
The radiative cooling of objects during daytime under direct sunlight has recently been shown to be significantly enhanced by utilizing nanophotonic coatings. Multilayer thin film…
Spray-pyrolysis deposited La1-xSrxCoO3 thin films for potential non-volatile memory applications
Z. Viskadourakis, C. N. Mihailescu, G. Kenanakis
In this work thin films of the La1-xSrxCoO3 (0.05 < x < 0.26) compound were grown, employing the so-called spray pyrolysis process. The as-grown thin films exhibit polycrystalline…
Ultrafast modulation in a THz graphene-based flat absorber through negative photoconductivity
Anna C. Tasolamprou, Anastasios D. Koulouklidis, Christina Daskalaki +9
We present the experimental and theoretical study of an ultrafast graphene based thin film absorption modulator for operation in the THz regime. The flat modulator is composed of a…
The Software-Defined Metasurfaces Concept and Electromagnetic Aspects
Anna C. Tasolamprou, Alexandros Pitilakis, Odysseas Tsilipakos +17
We present the concept and electromagnetic aspects of HyperSurFaces (HSFs), artificial, ultrathin structures with software controlled electromagnetic properties. The HSFs key unit…
