Photoelectric Effect-practical applications

[MeenaAttota]

So after studying the photoelectric effect, I was really curious about why scientists would want to eject electrons from an atom in the first place. So, what would be the practical applications for ejecting electrons, or accelerating or directing electrons within an electric field?

There are so many applications we can see of the photoelectric effect and it's really cool. In solar cells, the photoelectric effect generates electricity, while electron microscopy and particle accelerators use high-speed electrons to study tiny structures and fundamental particles. X-ray production and radiotherapy leverage accelerated electrons for imaging and cancer treatment. Additionally, older CRT displays and electron beam lithography for semiconductor manufacturing rely on directed electrons to create images and precise patterns. These aren't all the uses but some of the few ways in which it can be applied.
