Moura Photovoltaic Power Station Moura Photovoltaic Power Station The Moura Photovoltaic Power Station (also known as Amareleja Photovoltaic Power Station) is a large photovoltaic power station in Amareleja, in the municipality of Moura, Portugal. It is one of the largest power stations of its kind, and is built in one of the sunniest regions in Europe. Its construction involved two stages: stage 1 was completed in 2008 after 13 months, and stage 2 was completed in 2010. The entire project topped a total cost of €250 million. Stage 2 of the project involved the construction of a further 20 MW of solar panels. It
Photovoltaic effect Photovoltaic effect The photovoltaic effect is the creation of voltage and electric current in a material upon exposure to light and is a physical and chemical phenomenon. The photovoltaic effect is closely related to the photoelectric effect. In either case, light is absorbed, causing excitation of an electron or other charge carrier to a higher-energy state. The main distinction is that the term "photoelectric effect" is now usually used when the electron is ejected out of the material (usually into a vacuum) and "photovoltaic effect" used when the excited charge carrier is still contained within the material. In either case,
