PURPOSE:To prevent the peeling of a protective layer formed on an organic photovoltaic element, in the case of long term application, and realize long life. CONSTITUTION:The title organic photovoltaic element has a structure wherein an electron accepting organic material layer and an electron donating organic material layer which form a rectification junction are laminated between two electrodes at least one of which is transparent. A protective film whose main component is carbon is formed on the surface of the element. The film contains hydrogen, oxygen and nitrogen wherein the atomic weight ratio of nitrogen and carbon (N/C ratio) is lower than or equal to 0.005. |
