  • Patent number: 8338903
    Abstract: The surrounding length of a junction separation portion can be shortened to improve an insulating resistance in order to provide a solar cell with highly efficiency. In a photoelectric transducer of the type where a light-receiving surface electrode is wired to another electrode on a back surface via a through electrode passing through a semiconductor substrate of a first conductive type, the photoelectric transducer comprises: a junction separation portion made around the through electrode on a back surface of the semiconductor substrate; a dielectric layer formed for covering the junction separation portion, the through electrode penetrating the dielectric layer; and a back electrode provided on the dielectric layer and coupled to the through electrode which is connected to the light-receiving surface electrode.
