Meaning
A photoelectric cell that uses a strip of selenium.
Classification
Nouns denoting man-made objects.
Examples
- The first selenium cell was created by Willoughby Smith in 1873, and it consisted of a strip of selenium in contact with two metal electrodes.
- The selenium cell was more sensitive to light than other early photoelectric cells due to its composition and structure.
- To create a basic light sensor, scientists often used a selenium cell connected to a simple circuit.
- A notable advantage of the selenium cell was its ability to change electrical resistance in response to varying light intensities.
- Historical photoelectric cells like the selenium cell led to significant developments in light-sensitive technologies.
