“Solar energy” it’s considered as a serious energy source for many years; it’s harnessed by modern technology called Photovoltaic (PV). Photovoltaic is best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to photons of light exciting electrons into a higher state of energy, allowing them to act as charge carriers for an electric current. The photovoltaic effect was first observed by Alexandre-Edmond Becquerel in 1839. Continue reading Learn about solar energy and its benefit.
