Solar battery cell and production method thereof

Abstract

A method for producing a solar battery cell, includes: a first step of forming an insulating film on one face side of a semiconductor substrate; a second step of forming an electrode forming groove in an electrode forming region on the insulating film; a third step of printing an electrode printing paste including metal particles as a main component to a width that covers the electrode forming groove and a region sandwiching the electrode forming groove on the insulating film and that is wider than a width of the electrode forming groove, and then drying the electrode printing paste; and a fourth step of forming an electrode with the width of the electrode forming groove by firing the electrode paste at a temperature that is equal to or higher than a melting point of the metal particles or that is equal to or higher than a eutectic temperature, and accumulating and solidifying the electrode paste on the electrode forming groove.
