Electro-conductive paste comprising metal compound

In general, the present invention relates to electro-conductive paste comprising a metal additive and solar cells obtainable therefrom by application of the paste to a p-type doped face. More specifically, the present invention relates to electro-conductive pastes, solar cell precursors, processes for preparation of solar cells, solar cells and solar modules. The present invention relates to a precursor comprising 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, a conductive paste comprising the following paste constituents: i, at least about 70 wt% Ag particles, based on the paste, ii, a vehicle, iii, 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 conductive paste b, is superimposed on a p-type doped face. 本发明般性地涉及包含金属添加剂的导电糊以及可以通过将该糊施加于p型掺杂面上而由其得到的太阳能电池。更具体而言，本发明涉及导电糊、
