PROBLEM TO BE SOLVED: To provide electro-conductive paste comprising a metal additive and a solar cell obtainable therefrom by application of the paste to a p-type doped face.SOLUTION: A precursor is provided that comprises the following paste constituents: a. A Si wafer with at least one p-type doped face and at least one n-type doped face; b. An electro-conductive paste comprising the following paste constituents: i. at least about 70 wt. % Ag particles, based on the paste, ii. a vehicle, iii. a glass, iv. a metal compound comprising a metal M and which is one or more selected from the group consisting of: an organic metal oxide, a metal oxide, an organic metal compound and a silver metal oxide; wherein the electro-conductive paste b. is superimposed on a p-type doped face.SELECTED DRAWING: Figure 3b |
