External photoeffect and its significance in modern physics

The topic of this study is devoted to the external photoelectric effect, a phenomenon in which light, acting on a material, causes electrons to be knocked off its surface. The external photoelectric effect is an important element of quantum physics and is widely used in various fields, including photonic technologies and solar cells. This study examines the mechanisms of the external photoelectric effect, the effect of light on the behavior of electrons in various materials, as well as ways to increase the effectiveness of the photoelectric effect for practical applications.
