Photoelectric cell converts light energy into electric energy.

A photoelectric cell converts light energy into electrical energy. It works based on the photoelectric effect, a phenomenon where light falling on a material (usually a metal or semiconductor) causes the emission of electrons. These emitted electrons generate an electric current in the circuit connected to the cell.

When light strikes the surface of the material inside the photoelectric cell, the energy from the light photons is absorbed by the electrons in the material. If the light has enough energy (greater than or equal to the material's work function), the electrons are freed from the surface. This flow of electrons creates a current, which can then be used for various applications like powering devices, measuring light intensity, or in solar panels to generate electricity.

In summary, a photoelectric cell efficiently transforms light into electrical energy, making it a key component in modern technology like solar energy systems, light meters, and automatic doors.
