Abstract: A method for manufacturing a solar cell is disclosed. The disclosed method includes conductive region formation of forming a first-conduction-type region at one surface of a semiconductor substrate and a second-conduction-type region at another surface of the semiconductor substrate, and electrode formation of forming a first electrode connected to the first-conduction-type region and a second electrode connected to the second-conduction-type region. In the conductive region formation, the first-conduction-type region is formed by forming a dopant layer containing a first-conduction-type dopant over the one surface of the semiconductor substrate, and heat-treating the dopant layer, and the second-conduction-type region is formed by ion-implanting a second-conduction-type dopant into the semiconductor substrate at the another surface of the semiconductor substrate.

Abstract: Discussed is a method of manufacturing a heterojunction solar cell, including: forming a metal compound on a semiconductor substrate; forming a transparent conductive oxide on the metal compound; forming an electrode forming material on the transparent conductive oxide; and sintering the electrode forming material using light sintering to form an electrode part. The transparent conductive oxide may be sintered by light sintering to form a transparent conductive oxide layer formed of the transparent conductive oxide.
