Does silicon photovoltaic cells use the internal photoelectric effect
What Is The Photoelectric Effect? » ScienceABC
The photoelectric effect has a number of applications, but the most obvious, and also the biggest, example would be its use in producing solar energy using photovoltaic cells. These cells are made of semiconducting material that generate electricity when exposed to the sun.
What is the photoelectric effect of solar cells? | Silicon Solar
The photoelectric effect is the principle referring to when electrons are released by photons making an electrical current, which is what makes it possible for the harvesting of electricity through the use of solar cells.
6.3: Photoelectric Effect
Characteristics of the Photoelectric Effect. The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency.
