STACK-TYPE PHOTOVOLTAIC ELEMENT AND METHOD OF MANUFACTURING STACK-TYPE PHOTOVOLTAIC ELEMENT

摘要

A stack-type photovoltaic element with improved conversion efficiency having an intermediate layer and a method of manufacturing the same are provided. A stack-type photovoltaic element according to the present invention includes a first photovoltaic element portion (a) and a second photovoltaic element portion from a substrate side, as well as at least one intermediate layer between the first photovoltaic element portion and the second photovoltaic element portion. The intermediate layer is formed from a metal oxide film having an oxygen atom concentration/metal atom concentration ratio not lower than 0.956 and not higher than 0.976.
