Harnessing the power of the sun through solar cells is a remarkable way to generate electricity, and it’s becoming increasingly popular. At their core, solar cells operate by converting sunlight directly into electricity through a process known as the photovoltaic effect. This technology is both straightforward and ingenious.
And all this is possible thanks to an essential component: the photovoltaic cell. A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect.
The photovoltaic effect is the fundamental process by which solar cells generate electricity. It occurs when photons, or light particles, strike a solar cell, primarily affecting the semiconductor material, usually silicon.
A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect. Major milestones in the history of the development of these cells, include:
The photovoltaic conversion process is fundamentally about light interacting with the atoms of a semiconductor material. In a solar cell, when light photons strike the material, enough energy is imparted to dislodge electrons from the material's atoms, creating an electron-hole pair.
A PV solar panel is a collection of solar cells electrically connected together and mounted in a frame — a solar array. Each solar cell generates a relatively small amount of electricity, but collectively, the power generated by multiple cells adds up.
