Title:
光電変換素子とその製造方法
Document Type and Number:
Japanese Patent JP7102532
Kind Code:
B2
Abstract:
A photoelectric conversion element (1) in an embodiment includes: a first photoelectric conversion layer (3A) including: a bottom electrode (4A); a photoelectric conversion layer (5A); and a top electrode (6A); and a second photoelectric conversion part (3B) including: a bottom electrode (4B); a photoelectric conversion part (5B); and a top electrode (6B). A conductive layer (14) is formed on the bottom electrode (4B). The top electrode (6A) and the bottom electrode (4B) are electrically connected by a conductive portion and the conductive layer (14), the conductive portion formed of a part of the top electrode (6A) filled in a first groove (11) that makes a surface of the conductive layer (14) exposed and separates a photoelectric conversion layer (5A) and a photoelectric conversion layer (5B) from each other. The top electrode (6A) and the top electrode (6B) are physically separated by a second groove (12) provided to make a step surface of a stepped portion (17) that is provided in the photoelectric conversion layer (5B) exposed and have a bottom surface thereof overlap the surface of the conductive layer (14).
