ABSTRACT:
A buried contact solar cell which is capable of operating with high efficiency is manufactured by a method which comprises the steps of forming a groove in a surface of a substrate, and forming an electrode by filling a conductive material in the groove using a laser. The step of forming the electrode may include positioning a conductive thin plate above the surface of the substrate, melting the conductive thin plate using a laser in a pattern corresponding to the groove, filling the conductive material in the groove, and removing the conductive thin plate.
