Photovoltaic Technologies With the evolution of society, the necessity of alternative energy sources, that suit in what sustainable development requires is more evident throughout the years. Since the reduction of the emission of gases that cause the greenhouse effect, for example, is an important factor. The sun is the planet’s primary energy. It is responsible for practically all of the observable natural processes. Thus, nowadays, technologies that have the sun as a source have been considered, studied and utilized. The photovoltaic technologies are an example of how it is practicable to obtain energy from the sun. These TECHNOLOGIES have been developed throughout the years and it is one of the main hopes of clean and renewable energy in the present. In the other side, they are one of the most expensive too. The solar energy is the most abundant energy resource on the planet, and at the same time, it is unlimited. According to a report on renewable energy published by the Intergovernmental Panel on Climate Change (IPCC, 2011), that furnishes estimates of global technical potential of renewable energy sources based in a large number of studies, the lowest estimate of the technical potential for direct solar energy is bigger than the actual global primary energy supply (because of their multiple use, direct solar energy and biomass are designated as primary energy), and it is also bigger than the highest estimate of any other renewable energy potential. The solar
