PHOTOVOLTAIC ELEMENT AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2017/017771

A1

Provided are: a photovoltaic element that has a low contact resistance in a collecting electrode, and that can increase conversion efficiency since the collecting electrode is formed with thin wires; and a method for manufacturing the photovoltaic element. The photovoltaic element is provided with: a layer structural body that has a transparent conductive film at least as an outermost layer on one side and that generates an electromotive force through photoirradiation; and a linear collecting electrode arranged on the outer surface of the transparent conductive film. The collecting electrode is characterized by having: a barrier layer that is layered on the outer surface of the transparent conductive film and that contains silver, copper, and at least one of palladium and gallium; and a copper layer that is layered on the outer surface of the barrier layer and of which the main ingredient is copper. The layer structural body preferably further has: a p-type or n-type crystal semiconductor substrate; a first true amorphous semiconductor layer and a p-type amorphous semiconductor layer that are layered in this order on one surface side of the crystal semiconductor substrate; and a n-layer side intermediate layer and a n-type amorphous semiconductor layer that are layered in this order on the other surface side of the crystal semiconductor substrate.
