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…
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…
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…
Phase memory preserving harmonics from abruptly autofocusing beams
Anastasios D. Koulouklidis, Dimitris G. Papazoglou, Vladimir Yu. Fedorov +1
We demonstrate both theoretically and experimentally that the harmonics from abruptly auto-focusing ring-Airy beams present a surprising property, they preserve the phase distribut…
Generation of intense terahertz radiation by two-color filamentation of laser pulses with different wavelengths
Vladimir Yu. Fedorov, Stelios Tzortzakis
We theoretically study the generation of terahertz (THz) radiation by two-color filamentation of ultrashort laser pulses with different wavelengths. We consider wavelengths in the…
