Definition of photoelectric in English:



  • Characterized by or involving the emission of electrons from a surface by the action of light.

    ‘photoelectric detection systems’
    • ‘It soon became clear in the next few years that the particles emitted in the photoelectric effect were indeed electrons.’
    • ‘A structure or space in the shadow of an efficient photoelectric generator surface already possesses this characteristic.’
    • ‘A solar cell uses the photoelectric effect to create an energy imbalance within the cell which can be used to drive some load.’
    • ‘Materials of high atomic energy may exhibit photoelectric absorption, the energy of gamma rays is then transferred to an electron, which is then ejected from the atomic shield.’
    • ‘Too much of the potential triggering energy of the degraded gammas is dissipated in Compton and photoelectric interactions.’
