摘要
The invention relates to an electro-conductive paste comprising an inorganic reaction system with a high glass transition temperature 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 with at least one hole with a Si surface;ii) an electro-conductive paste 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 the inorganic reaction system has a glass transition temperature above 550° C.展开▼
