Japan Photovoltaic Energy Association Japan Photovoltaic Energy Association Japan Photovoltaic Energy Association (JPEA) is the best-known body for solar photovoltaic energy companies in Japan. Founded on April 23, 1987, it has a number of objectives and activities, one of which is providing the JPEC certification for solar modules in the Japanese market. The association serves as a spokesperson for the photovoltaics energy industry in Japan. JPEA set a pathway for the photovoltaic industry in Japan to reach 100 GW by 2030, from roughly 30 GW in 2015. The group comprises multiple companies in the industry, and reported a 13% drop in total photovoltaic solar
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,
