PHOTOELECTRIC ELEMENT AND METHOD OF MANUFACTURING PHOTOELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a photoelectric element that reduces recombination loss of carriers due to defects of a semiconductor substrate and improves an open-circuit voltage, and to provide a method of manufacturing the photoelectric element.SOLUTION: A photoelectric element includes: a semiconductor substrate composed of single crystal silicon and having a first surface and a second surface facing to each other; a doping portion formed on a first surface side of the semiconductor substrate; and a first insulating film formed between the doping portion and the second surface of the semiconductor substrate. The doping portion includes a first semiconductor layer containing a first dopant doped into the single crystal silicon and a second semiconductor layer containing a second dopant doped into the single crystal silicon.
