Solar cell, method for manufacturing dopant layer, and method for manufacturing solar cell

摘要

In a method of manufacturing a solar cell (100) includes forming a dopant layer (20) by doping with a dopant (202) of a first conductivity type and a counter dopant (204) of a second conductivity type opposite to the first conductivity type to a surface of a semiconductor substrate. Here, a doping amount of the counter dopant (204) is less than a doping amount of the dopant (202).
