Photovoltaics years in Northern Europe. The term "photovoltaic" comes from the Greek φῶς ("phōs") meaning "light", and from "volt", the unit of electro-motive force, the volt, which in turn comes from the last name of the Italian physicist Alessandro Volta, inventor of the battery (electrochemical cell). 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 Conference Volta Conference The Volta Conference was the name given to each of the international conferences held in Italy by the Royal Academy of Science in Rome, and funded by the Alessandro Volta Foundation. In the interwar period, they covered a number of topics in science and humanities, alternating between the two. The first conference, held at Lake Como in 1927, led to the public introduction of the uncertainty principle by Niels Bohr and Werner Heisenberg. The second conference did not take place until 1932; its topic was "Europe", and it was notable for the participation of a number of mainly
