Re-emitting oxide – copper iodide(I) films for silicone solar cells

Журнал Белорусского государственного университета: Химия, 2021
The effect of Al2O3 – CuI oxide films on the photoelectric parameters of silicon solar cells (SCs) has been studied. The largest increase in the external quantum efficiency of photoelectric conversion of SCs in the near UV range is observed for monolayer

Photoelectric Polarimetry and the Gas Pixel Detector Yesterday, Today and Tomorrow

Galaxies, 2018
Since the very beginning of X-ray Astronomy, polarimetry has been suggested as a tool of diagnostics, of great potentiality. While almost all measurements of X-rays were based on detectors using the photoelectric effect, the first attempt to perform ...

Atmospheric Escape of Close-in Giants around Hot Stars: Far-Ultraviolet Radiation and Photoelectric Heating Effect [PDF]

arXiv, 2020
Atmospheric escape is an important process that controls the long-term evolution of close-in planets. We perform radiation hydrodynamics simulations of photo-evaporation of exoplanets' atmospheres to study the effect of photoelectric heating by far-ultraviolet (FUV) radiation. Specifically, we consider a close-in hot Jupiter around a hot A-star.

Photoelectric Emission from Dust Grains Exposed to Extreme Ultraviolet and X-ray Radiation [PDF]

Astrophys.J. 645 (2006) 1188-1197, 2006
Photoelectric emission from dust plays an important role in grain charging and gas heating. To date, detailed models of these processes have focused primarily on grains exposed to soft radiation fields. We provide new estimates of the photoelectric yield for neutral and charged carbonaceous and silicate grains, for photon energies exceeding 20 eV.
