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
