History of Photovoltaics:
The French physicist A. E. Becquerel first observed the photovoltaic effect in 1839. The photovoltaic effect is the creation of electrical voltage and current when a material is exposed to photons from the sun. “Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material.”
Photovoltaics, or, Solar Energy, is really quite amazing because the sun is such an abundant resource. With new silicone recycling programs and higher efficiency in solar modules as well as lowering costs of solar systems, solar energy is expected to become a leading source of energy on a global scale. In fact,2013 is the first year that solar has surpassed wind energy in installed GW capacity on a global scale.
