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.

What type of energy uses the photoelectric effect?
Solar energy uses the photoelectric effect to convert light energy into electrical energy. When sunlight shines on a solar panel, the photoelectric effect causes electrons to be released, creating an electric current.
What is the relationship between frequency and kinetic energy in photoelectric effect?
In the photoelectric effect, increasing the frequency of incident light increases the kinetic energy of the emitted electrons. This is because higher frequency light photons carry more energy, which can be transferred to the electrons during the photoelectric effect.
Is photoelectric absorption high kvp?
No, photoelectric absorption decreases with increasing photon energy (kVp). This is because higher-energy photons are more likely to be transmitted through the material or undergo Compton scattering rather than being absorbed through the photoelectric effect.
Why photoelectric measurement are so sensitive to the nature of photoelectric surface?
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
Why X-rays are inverse of photoelectric effect?
X-rays and the photoelectric effect are related because X-rays are high-energy electromagnetic waves that can cause the photoelectric effect to occur in matter, where electrons are ejected from atoms when X-rays are absorbed. This happens because X-rays have enough energy to overcome the binding energy of the electrons in the atoms they interact with. So, in essence, X-rays can trigger the photoelectric effect in materials due to their high energy levels.

Is photoelectric renewable or nonrenewable?
It is considered renewable. It photoelectric energy is created when the sun shines.

Which of photoelectric transducer is used for production of electric energy by converting solar energy?
photo emission cell
What is the significance of the maximum kinetic energy of photoelectrons in the context of photoelectric effect?
The maximum kinetic energy of photoelectrons in the photoelectric effect is significant because it helps determine the energy of the incoming photons. This energy is crucial in understanding how light interacts with matter and can provide insights into the properties of materials.
What does light produce in the photoelectric effect?
Light produces electrons in the photoelectric effect. When light of sufficient energy (photon energy) shines on a metal surface, it can eject electrons from the surface, creating a flow of current.
What is Einstein's photoelectric equation?
E(photon energy)=K.E+Work Function
On what factors does photoelectric current depends?
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
