Example: Photoelectric Effect

Here we work through an example to find the maximum kinetic energy of ejected electrons when a metal with a particular work function is illuminated by a broadband source.

Excellent video with great explanations!

So, is photoelectric effect somehow similar to thermionic emission, please?
Because in both cases the electrons need enough kinetic energy to overcome the metal work function?
Many thanks!
