Solar Cell
The solar cell works in several steps:
photon in sunlight hit the solar panel and are absorbed by semiconducting material, such
as silicon.
Electrons are excited from their current molecular/atomic orbital. Once excited an
electron can either dissipate the energy as heat and returns to its orbital or travel
through the cell until it reaches an electrode. Current flows through the material to
cancel the potential and this electricity is captured. The chemical bondsof the material
are vital for this process to work, and usually silicon is used in two layers, one layer
being doped with boron, the other phosphorous. These layers have different chemical
electric charges and subsequently both drive and direct the current of electrons.
An array of solar cells converts solar energy into a usable amount of direct current (DC)
electricity.
An inverter can convert the power to (AC).
Thank you
