STACKED PHOTOVOLTAIC ELEMENT AND METHOD FOR MANUFACTURING STACKED 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 (100) according to the present invention includes a first photovoltaic element portion (3) and a second photovoltaic element portion (5) from a substrate (1) side, as well as at least one intermediate layer (7) between the first photovoltaic element portion (3) and the second photovoltaic element portion (5). The intermediate layer (7) 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.
