DENIS LENARDIC

The term photovoltaics derives from the Greek word phōs meaning light and the word volt, named by italian physicist Alessandro Volta (1745-1827). Photovoltaics is a science, which examines light-electricity conversion, respectively, photon energy-electric current conversion. In other words it stands for light-current conversion. First known use of word photovoltaic in the literature was in the book Elements of Electro-biology, Or the Voltaic Mechanism of Man of Electro-pathology, Especially of the Nervous System and of Electro-therapeutics written by Alfred Smee (1818-1877) in 1849. Smee was surgeon, but he also significantly contributed to progress of electro-metallurgy and electrical physiology... The light to current conversion takes place within solar cells, which can be amorphous, polycrystalline or monocrystalline, according to their structure. In most cases they are made of silicon. Solar-module consists of many solar cells, which are electrically connected and placed between..
