Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.
When sunlight strikes the cell, it generates an electric current by knocking electrons loose from atoms within the material. Multiple solar cells are combined to form a solar panel, which can produce a substantial amount of solar electricity. Why is Solar Cell Called a “ Cell “?
Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths of the solar spectrum. A PV cell is made of semiconductor material.
At the heart of solar power generation are photovoltaic (PV) cells, which convert sunlight into renewable electricity. These specialised cells utilise the photovoltaic effect to generate an electric current when sunlight strikes them, exciting electrons in the semiconductor material like silicon.
Solar cells, also known as photovoltaic (PV) cells, are semiconductor devices that convert sunlight directly into electricity. This process is known as photovoltaic effect. Solar energy has now become extremely popular because it is sustainable and renewable and has very low impact on environment.
Most commonly, solar energy is captured and converted into electricity using solar cells. These cells are designed to absorb sunlight and convert it directly into electrical power without any moving parts, making them highly reliable and low-maintenance.
