A solar cell element according to one embodiment of the present invention comprises: a semiconductor substrate; an antireflection film disposed in a first region on one main surface of the semiconductor substrate; and a front surface electrode which is disposed in a second region on the one main surface of the semiconductor substrate, comprises silver as a main component and contains a tellurium-based glass containing tellurium, tungsten, and bismuth as essential components. A method for manufacturing the above solar cell element comprises: a first step of forming the antireflection film on the one main surface of the semiconductor substrate; a second step of printing on the antireflection film a conductive paste containing a conductive powder comprising silver as a main component, a tellurium-based glass frit containing tellurium, tungsten, and bismuth as essential components, and an organic vehicle; and a third step of disposing the antireflection film in the first region of the semiconductor substrate and forming the front surface electrode in the second region of the semiconductor substrate, by firing the conductive paste and eliminating the antireflection film positioned under the conductive paste. |
