Abstract
The conductive paste according to the present invention, used when forming an n-type layer formed on one surface of a p-type silicon semiconductor substrate and a conducting electrode, is characterized in that the conductive paste comprises silver powder, glass frit, silver phosphate and an organic vehicle, and the mixing ratio of the glass frit per 100 weight units of silver powder is within the range of not less than 1 weight unit and not more than 5 weight units and the mixing ratio of the silver phosphate per 100 weight units of silver powder is within the range of not less than 0.5 weight units and less than 5 weight units. As a result, a conductive paste with which large-scale reduction of the labor required when forming electrodes is obtained, a solar cell in which grid electrodes comprising this conductive paste are formed, and a fabrication method for the same are provided.
