photovoltaic cells . select one: a. are increasingly costly produce which precludes major commercial application b. rely on the electrical current produced when silicon is struck by sunlight c. require an outside source of electricity to generate electricity on their own d. have small rotational generators built into every cell

The rotor shaft of a generator is spun or rotated by the fluid's force on the blades.

What do you meant by silicon is struck?

When sunlight strikes a solar cell, electrons in the silicon are expelled, causing the silicon to generate "holes"—the voids the departing electrons left behind.

Electrons will be moved to the n-type layer and holes to the p-type layer if this occurs in the electric field. The bonds [between silicon atoms] in a crystal are created by electrons that are shared by all of the atoms in the crystal.

One of the electrons in one of the bonds is stimulated to a higher energy level by the absorption of the light and is thus given more freedom to move than when it was bound. Silicon is the chosen photovoltaic (PV) material because it has a high absorption rate and can generate power from solar energy.
