Comprehensive techno-economic analysis of solar photoelectric materials of different generations [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение"
A possible solution to the global energy crisis is to use sunlight to generate electricity. Solar cells that convert solar energy into electricity have to be reliable and cost-effective to compete with conventional energy sources.

Constraint on intergalactic dust from thermal history of intergalactic medium [PDF]

open access: yes, 2002
This Letter investigates the amount of dust in the intergalactic medium (IGM). The dust photoelectric heating can be the most efficient heating mechanism in the IGM where the density is very small and there are a lot of hard ultraviolet photons ...

Investigation of the Profiles of High School Students’ Mental Models of the Concept of Photoelectric Effects

open access: yesScientiae Educatia: Jurnal Pendidikan Sains, 2020
A mental model was students’ internal representation when they learned a concept. The conceptual model is a description of natural phenomena following the views of scientists. Most high school students have an idea of classical physics on understanding

The nuclear photoelectric effect [PDF]

open access: yesProceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935
Some time ago we reported in ‘Nature’ the observation of a nuclear photo-effect, the disintegration of the deutron by γ-rays. An effect of y-rays upon complex nuclei might be expected to occur from analogy with the phenomena of excitation and ionization of atoms by light, and such an effect has been looked for from time to time by various ...

Photoelectric Effect in Uranium [PDF]

open access: yesJournal of the Physical Society of Japan, 2006
We report the work function Φ for single and polycrytalline α-uranium over the temperature range 173 ≤ T ≤873 K. Photoemission spectroscopy (PES) measurements were made at energies 21 eV and 40 eV. Surfaces were prepared in situ by sputter/annealing cycles under UHV conditions.

On the photoelectric quantum yield of small dust particles

open access: yes, 2016
Photoelectron emission is crucial to electric charging of dust particles around main-sequence stars and gas heating in various dusty environments. An estimate of the photoelectric processes contains an ill-defined parameter called the photoelectric ...
