Summary:PROBLEM TO BE SOLVED: To improve the characteristics of a photoelectric conversion device in which a heterojunction back contact cell is electrically connected to a wiring sheet.SOLUTION: A photoelectric conversion device comprises a heterojunction back contact cell (10) and a wiring sheet (20). The heterojunction back contact cell (10) comprises a semiconductor substrate (1) of a first conductivity type or a second conductivity type, an amorphous semiconductor film (3) of a first conductivity type, an amorphous semiconductor film (5) of a second conductivity type, a first electrode (11), and a second electrode (12). The wiring sheet (20) comprises an insulating base material (21), and a first wiring (22) and a second wiring (23) on the insulating base material (21). The first electrode (11) is electrically connected to the first wiring (22). The second electrode (12) is electrically connected to the second wiring (23). The photoelectric conversion device satisfied at least one of the relation in which the width (W1) of the first electrode (11) is not less than the width W3 of the first wiring (22) and the relation in which the width W2 of the second electrode (12) is not less than the width W4 of the second wiring (23).SELECTED DRAWING: Figure 1 【課題】配線シートにヘテロ接合型バックコンタクトセルが電気的に接続された光電変換装置の特性を向上する。【解決手段】光電変換装置は、ヘテロ接合型バックコンタクトセル(10)と配線シート(20)とを備えている。ヘテロ接合型バックコンタクトセル(10)は、第1導電型または第2導電型の半導体基板(1)と、第1導電型非晶質半導体膜(3)と、第2導電型非晶質半導体膜(5)と、第1電極(11)と、第2電極(12)とを備えている。配線シート(20)は、絶縁性基材(21)と、絶縁性基材(21)上の第1配線(22)と第2配線(23)とを備えている。第1電極(11)は第1配線(22)に電気的に接続されている。第2電極(12)は第2配線(23)に電気的に接続されている。第1電極(11)の幅W1が第1配線(22)の幅W3以上であること、および第2電極(12)の幅W2が第2配線(23)の幅W4以上であることの少なくとも一方の関係が満たされている。【選択図】図1
