ABSTRACT:
A photovoltaic element includes a collecting electrode formed via a transparent conductive film on a semiconductive layer having a semiconductor junction, wherein a conductive film is disposed on the collecting electrode. A modular structure is adopted in which a plurality of photovoltaic elements having such a structure are connected in series via a tab soldered onto the conductive film. On a light-transmission side, a conductive film is disposed to cover an entire surface of the transparent conductive film. This conductive film is allowed to act as a reflection film on a back surface side. A screen printing process is repeated for a plural number of times so that the collecting electrode is formed with a flattened surface.
