It is quite expensive, compared to the energy you get from your power company. Just a common car battery for storing the energy - an essential part of such a system - costs you more, for each watt-hour, than what you pay the power company, since the battery doesn't last forever. Such a system is still useful in places that are not connected to the regular power grid.
The photoelectric effect is a phenomenom that occurs when you fire a photon with high enough energy aggainst matter, and it expells an electron after absorbing the photon's energy.

One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.
why are photoelectric measurements are so sensitive to the nature of the photoelectric surface
It is considered renewable. It photoelectric energy is created when the sun shines.

When light falls onto a photoelectric cell electricity is produced.
