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
Alessandro Striggio Alessandro Striggio Alessandro Striggio (c. 1536/1537 – 29 February 1592) was an Italian composer, instrumentalist and diplomat of the Renaissance. He composed numerous madrigals as well as dramatic music, and by combining the two, became the inventor of madrigal comedy. His son, also named Alessandro Striggio, wrote the libretto for Monteverdi's "Orfeo". Striggio senior was born in Mantua, evidently to an aristocratic family. Records of his early life are sparse, but he must have gone to Florence as a young man. He began working for Cosimo de' Medici on 1 March 1559 as a musician, eventually to replace Francesco Corteccia
