Abstract
In a solar cell element including a silicon substrate that includes a p-type semiconductor region in a surface thereof and an electrode that is located on the p-type semiconductor region and based on aluminum, the electrode includes a glass component containing vanadium oxide, tellurium oxide, and boron oxide, the glass component having a vanadium oxide content smaller than the sum of a tellurium oxide and a boron oxide content. Alternatively, the electrode includes a glass component containing vanadium oxide, tellurium oxide, and boron oxide, the glass component containing 5 to 33 parts by mass of vanadium oxide, 4 to 30 parts by mass of tellurium oxide, and 4 to 18 parts by mass of boron oxide based on 100 parts by mass of the glass component.
