Abstract
A photovoltaic element comprising an electrode comprising an electrically conductive core member which is coated with a conductive adhesive fixed on the light incident surface of a photoactive semiconductor layer, via the conductive adhesive, is disclosed. The conductive adhesive is composed of at least two layers. The softening point of the conductive adhesive layer nearer to the core member is higher than the highest temperature encountered in the manufacture of the photovoltaic element.
Claims32
A photovoltaic element comprising an electrode comprising an elongated electrically conductive core member coated with a conductive adhesive fixed on the light incident surface of a photoactive semiconductor layer via said conductive adhesive, wherein said conductive adhesive is composed of at least two layers, and wherein the softening point of the conductive adhesive layer nearer to the core member is higher than the highest temperature encountered in the manufacture of said photovoltaic element.
A photovoltaic element comprising a semiconductor photoactive layer comprising at least one pin junction or pn junction and a collector electrode provided on the light incident side of said semiconductor layer, wherein said collector electrode comprises a metal wire coated with a layer of conductive resin which presents metal ions of the metal wire from diffusing into the semiconductor photoactive layer.
