In simple terms, we would look at the word broken down into roots. We have photo and electric. Photo means energy given by light, and electric means energy made through charged particles. Therefore, Photoelectric device would be a device that it's powered by electricity generated by light.
An example would be your ordinary calculator. The solar strip at the top is a photoelectric device.
an end device
Yes, it is also and input device. I/O device.
input device
A input device is when you put something into the computer. A output device is when something from a computer comes out, either a hard or soft copy. So, I think it would be a input device, because you are putting a direction to turn on!
computer is a electronic device
This might be a photoelectric device. Shine light on it and charges move.
The resistance of a selenium cell or other photoelectric device in total darkness.
The device you are referring to is a photoelectric cell or a photodiode. When light shines on the metal surface of these devices, electrons are emitted in a process called the photoelectric effect, which generates an electric current.
A photocell or photoelectric cell converts sunlight into electrical energy.
A solar panel is a device that absorbs the Sun's radiant energy and converts it into electricity through a photoelectric effect.
why are photoelectric measurements are so sensitive to the nature of the photoelectric surface
A photoelectric switch is a device that uses light to detect the presence of an object. It typically consists of a light source and a sensor that detects the light reflected back. When the object blocks the light, it triggers the switch to turn on or off, making it useful for automation and sensing applications.
There is the photoelectric effect, which is the process that emitts electrons from a metals surface when light of a certain frequency shines on the surface. In the metal, the nuclei are surrounded by electrons, so when the incoming electrons strike the surface, they pull apart from the electrons of the metal because of how like charges detract from each other.
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.

Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
