The term "photo-voltaic" has been in use in English since 1849. Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons by the photovoltaic effect. Solar cells produce direct current electricity from sunlight which can be used to power
Volta Prize the first practical electric motor used in industry. One of its most notable awards was made in 1880, when Alexander Graham Bell received the fourth edition of the Volta Prize for the invention of the telephone.
