Solar panels convert sunlight into electricity by utilizing the photovoltaic effect, which enables the direct conversion of sunlight into electrical energy. Harnessing the power of the sun, solar panels contain photovoltaic cells made of semiconductor materials that generate an electric current when exposed to sunlight.
Photovoltaic Cells: Solar panels are made up of photovoltaic cells, also known as solar cells, which are typically made from semiconductor materials such as silicon. Each photovoltaic cell consists of two layers of semiconductor material, one with a positive charge (p-type) and the other with a negative charge (n-type).

Absorption of Sunlight: When sunlight strikes the surface of a solar panel, it is absorbed by the semiconductor material. Sunlight is composed of photons, which are particles of light energy. When a photon strikes the surface of a solar cell, it transfers its energy to an electron in the semiconductor material.
Generation of Electric Current: The absorbed energy excites an electron in the semiconductor material, causing it to break free from its atom and create an electron-hole pair. The movement of these free electrons creates an electric current within the semiconductor material, known as a photocurrent.
Electric Field Formation: The electric current generated by the movement of electrons creates an imbalance of charges between the p-type and n-type layers of the semiconductor material, creating an electric field at the junction between the two layers.
