Electro-conductive pastes with salts with an anion consisting of halogen and oxygen in solar cell applications

摘要

In general, the present invention relates to electro-conductive pastes with salt additives with anions consisting of halogen and oxygen, and solar cells with high Ohmic sheet resistance, preferably photovoltaic solar cells. 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 an electro-conductive paste at least comprising as paste constituents:
a) metallic particles;
b) a glass frit;
c) an organic vehicle; and
d) a salt with an anion comprising an oxygen atom and a halogen atom.
