Abstract
A method of manufacturing a solar cell includes: providing an insulating layer on a semiconductor layer provided on at least a part of a principle surface of a semiconductor substrate; providing a mask layer on the insulating layer; removing a part of the mask layer by laser irradiation so as to form a first opening through which the insulating layer is exposed; and removing, by an etching agent, the insulating layer exposed through the first opening so as to form a second opening through which the semiconductor layer is exposed.
