PLEASE HELP!!!
Which event happens in a solar cell when the photoelectric effect occurs?
A. Electrons flow from the positively charged semiconductor to the negatively charged one.
B. Electromagnetic waves strike the transparent glass on the top of the cell, removing electrons from it.
C. A current forms when electromagnetic waves strike a semiconductor, removing some of its electrons.
D. The wave model of light is supported, but the particle model is not.

What is Photoelectric ?
When a substance absorbs electromagnetic radiation, a phenomenon known as the photoelectric effect causes electrically charged particles to be discharged from or within the material. When light strikes a metal plate, the action is frequently described as the ejection of electrons from the plate.
The phenomenon in a solar cell at the time of photoelectric effect :
When metal is exposed to light, electrons are ejected from its surface. The photoelectric effect is what is causing this process, and the electrons are known as photoelectrons. According to experiments, increasing light frequency increases the photoelectrons' kinetic energy, and intensifying the light increases current. The photoelectric effect happens when a solid material, like metal, is exposed to sunlight and electrons are released from its surface. Any substance that responds to exposure to sunshine is referred to as a photoemissive substance, and the ejected electrons are known as photoelectrons.
