The equivalent electrical circuit of a solar PV cell has a _______.

Solar cell

• The equivalent electrical circuit of a solar PV cell has a PN junction diode.
• A solar cell, also known as a photovoltaic (PV) cell, is an electronic device that converts sunlight directly into electricity through the photovoltaic effect.
• When sunlight (which consists of photons) strikes the surface of a solar cell, it is absorbed by the semiconductor material.
• The energy from the absorbed light excites electrons in the semiconductor, causing them to break free from their atoms. This creates electron-hole pairs.
• Solar cells have built-in electric fields that separate the electrons and holes. The electrons move towards the front surface of the cell, and the holes move towards the back surface.
• When the front and back surfaces are connected by an external circuit, electrons flow through the circuit, generating direct current (DC) electricity.
