Description

[0001] Cross References to Related Applications [0002] This application claims priority based on German Patent Application No. 102011 056 087.4 filed on December 6, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] Various embodiments of the invention relate to a solar cell screen printing composition, a solar cell, and a method of fabricating a metallization structure. Background technique [0004] To manufacture the backside metallization of solar cells, aluminum backside paste is usually printed on the backside of the solar cell by screen printing, and the aluminum backside paste printed on it is subsequently coated. Solar cell heating. To avoid bowing of the solar cell during cooling after heating due to the fact that the thermal expansion coefficient of the aluminum of the backside paste differs from that of the semiconductor material of the solar cell, the backside aluminum paste is highly porous. The porosity of the backside...
