The invention provides a method of preparing a metallization structure on a solar cell. The method includes patterning a first composition on a surface of a semiconductor substrate; and applying a second composition over the first composition. An area covered by the first composition is 5-95% of an area covered by the second composition. The semiconductor substrate is then subjected to firing conditions. The invention also provides a metallization structure formed using the method described herein.
