Photovoltaic, (PV) is a technology that converts light directly into electricity. Photovoltaic is also the field of study relating to this technology and there are many SANYO researchers devoted to work on photovoltaic. Due to the growing need for solar energy, the manufacture of solar cells and solar photovoltaic array has expanded dramatically in recent years. Photovoltaic production has been doubling every two years, increasing by an average of 48 percent each year since 2002, making it the world’s fastest-growing energy technology.
