pho·to·e·lec·tric

(fō'tō-ē-lek'trik),
Denoting electronic or electric effects produced by the action of light. See: photoelectric effect, photoelectric absorption.

(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.

Photoelectric sensors exist in numerous forms, such as cylindrical type, box type, and fiber-optic sensors, they can also be further segmented on the basis of light source, such as visible red, laser, and infrared.
DX is a sensitizing dye for dye sensitized solar cells developed by a team including Hiroshi Segawa Professor of Research Center for Advanced Science and Technology at the University of Tokyo, who is a key researchers in the Cabinet Office's Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST), and is a next-generation sensitizing dye able to efficiently absorb and perform photoelectric conversion of near infrared light(*1) that could not be absorbed by ruthenium sensitizing dyes used in the past.
So within 20 feet of those rooms, photoelectric detectors must be used, under the new regulations.
He was one of the first users of Norman Walker's JEAP photoelectric photometers and collaborated on a variety of projects with professional astronomers, most notably, Chris Lloyd (first at Herstmonceux and then at RAL).
Unlike conventional photoelectric sensors, however, Checker offers the following capabilities:
Banner Engineering offers the new World-Beam[R] Q12 Series ultra-miniature photoelectric sensors.
One of the many salacious historical kernels Clausen has unearthed concerns a never-built sound installation that would have paired a work by John Cage with the Lippold sculpture on the building's west entrance: "Cage devised a system whereby the movement of people going in and out of the lobby would activate photoelectric cells; these in turn would release Muzak .
Unlike photoelectric technology, these sensors are not affected by dust, light and color.
In 1905 the great scientist published his three landmark papers on Special Relativity, the Photoelectric Effect and Brownian motion which helped to lay the foundations of modern physics.
He explained a phenomenon called the photoelectric effect: When you shine a certain type of light beam on a metal plate, the light's energy causes the plate to eject electrons (negatively charged particles).
His work on the photoelectric effect, for which he was awarded the 1921 Nobel Prize in physics, led to vacuum-tube technology and, ultimately, solid-state physics, which is the basis of contemporary electronic devices.
