PHOTOELECTRIC CONVERSION ELEMENT

PROBLEM TO BE SOLVED: To provide a photoelectric conversion element having excellent durability while suppressing charging.SOLUTION: The photoelectric conversion element includes: a first conductive layer having a first substrate and a conductive layer formed on one face of the first substrate, where the conductive layer has at least one first conductive section; and a second conductive layer arranged on the outside of the first conductive layer and having at least one second conductive section. The photoelectric conversion element has at least one photoelectric conversion cell, the photoelectric conversion cell includes a first conductive section, a second substrate opposed to the first conductive section and an annular seal section for jointing the first substrate to the second substrate, and a first groove is formed between the first conductive layer and the second conductive layer. When viewing the photoelectric conversion element from a direction orthogonal to one face of the first substrate, an insulation layer is formed so as to surround the whole seal section in at least one photoelectric conversion cell, and the insulation layer covers the first conductive layer on the inside inner than an outer peripheral edge of the insulation layer, enters the first groove, covers a part of the second conductive layer, and exposes the residual section of the second conductive layer.SELECTED DRAWING: Figure 1 【課題】帯電を抑制しながら、優れた耐久性を有する光電変換素子を提供すること。【解決手段】第１基板と、第１基板の一面上に設けられる導電層とを有し、導電層が、少なくとも１つの第１導電部を有する第１導電層と、第１導電層の外側に設けられ、少なくとも１つの第２導電部を有する第２導電層とを有する光電変換素子であって、少なくとも１つの光電変換セルを有し、光電変換セルが、第１導電部と、第１導電部に対向する第２基板と、第１基板及び第２基板を接合させる環状の封止部とを有し、第１導電層と第２導電層との間には第１の溝が形成され、光電変換素子を第１基板の一面に直交する方向から見た場合に、少なくとも１つの光電変換セルにおける封止部全体を包囲するように絶縁層が設けられており、絶縁層が、絶縁層の外周縁よりも内側で第１導電層を覆い隠し、第１の溝に入り込むとともに第２導電層の一部を覆っており、第２導電層の残部が露出されている、光電変換素子。【選択図】図１
