(fō'tō-ĕ-lek'trik)
Denoting electronic or electric effects produced by the action of light.

photoelectric 

Pertaining to the interaction between radiation and matter resulting in the absorption of photons and the consequent emission of electrons.

photoelectric

pertaining to the electrical effects of light or other radiation.

photoelectric absorption
the basis of diagnostic radiology. The difference in absorption of x-ray energy by different tissues causes differences in electromagnetic energy arriving at the film.
