The compound word "photovoltaic" derives from the union of the Greek term "phos", light and "volt", unit of measurement of the potential difference. In fact, a system for the production of photovoltaic energy is a combined application of the photoelectric effect , which consists in the spontaneous emission of electrons by a surface that is hit by electromagnetic radiation and the Volta effect, according to which if two different metals are placed in contact a potential difference is established between them and therefore the possibility of generate electric current.
Einstein gave a famous "quantum" interpretation of the photoelectric effect in 1905, according to which the total energy of electromagnetic radiation is divided into discrete portions ("quanta" of light), which is transferred to the bodies on which it collides. In metals alkaline cells (such as silicon) the action of visible light from the sun's rays is sufficient to emit energy electrons. By exploiting both the photoelectric effect and the Volta effect, in 1954 the American scientists Paerson, Fuller and Chapin created the first cell. commercial photovoltaic in crystalline silicon.
Thanks to this technology, photons, i.e. the light that hits the surface of the cell exposed to solar rays, can be captured and channeled to produce electricity which can be either stored in a battery or transmitted into the traditional electricity distribution network. We are therefore talking about electrical energy (photovoltaic) produced using only the energy of solar radiation.
