A method for manufacturing a photoelectric conversion element and a photoelectric conversion element manufactured by the manufacturing method. The method includes the steps of forming a p-type impurity diffusion layer by diffusing boron into a silicon substrate, forming an oxidation control mask on a surface of the p-type impurity diffusion layer in an area corresponding to an area where an electrode for p-type is to be formed, forming a thermal silicon oxide film on the surface of the p-type impurity diffusion layer, exposing part of the surface of the p-type impurity diffusion layer by removing the oxidation control mask formed on the surface of the p-type impurity diffusion layer in the area corresponding to the area where the electrode for p-type is to be formed, and forming the electrode for p-type on the part of the surface of the p-type impurity diffusion layer exposed by the removal of the oxidation control mask.

Method for manufacturing photoelectric conversion element and photoelectric conversion element

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.
