摘要

The invention relates to an electro-conductive paste comprising both, a vanadium containing compound and a phosphorus containing material, in the preparation of electrodes in solar cells, particularly in the preparation of electrodes in MWT solar cells, particularly in the preparation of the metal wrap through, or plug, electrode in such solar cells. In particular, the invention relates to a solar cell precursor, a process for preparing a solar cell, a solar cell and a module comprising solar cells. The invention relates to a solar cell precursor at least comprising as precursor parts:i) a wafer (101) with at least one hole (315) with a Si surface (113);ii) an electro-conductive paste (105) at least comprising as paste constituents: a) metallic particles;b) an inorganic reaction system;c) an organic vehicle; andd) an additive;comprised by the hole, wherein: i) a vanadium containing compound; andii) a phosphorus containing material selected from the group consisting of elemental phosphorus, a phosphorus containing compound or both;are each present in the paste.
