Photocells produce direct current (DC) electrical output. This type of current flows in one direction and is commonly used in small electronic devices and solar panels.
A photocell is typically made from a semiconductor material such as silicon. When light strikes the semiconductor material, it generates an electric current, making it a key component in light-sensing devices.
Direct current (DC) is produced by an electric battery. This type of current flows consistently in one direction from the positive terminal to the negative terminal of the battery.
An electromagnet is produced by an electric current. When an electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
Alternating current is produced by generators or power plants that use magnetic fields to induce voltage and generate electricity. This type of current changes direction periodically, typically in a sinusoidal waveform.
The two energy bands in which current is produced in silicon are the valence band and the conduction band. Electrons in the valence band can be excited to the conduction band by absorbing energy, allowing them to move and create an electric current.

Alternators usually produce AC current but in an automobile the current is fed through diodes which coverts it to DC power that the car can use.
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia
