ELECTRODE FOR A SOLAR CELL, MANUFACTURING METHOD THEREOF, AND SOLAR CELL

摘要

The present invention provides an electrode for a solar cell, in which the electrode is printed using a binder with a low Tg (hereinafter, referred to as a low Tg binder) to improve contact between a substrate such as a silicon wafer, or the like, and a conductive electrode material, and subsequently, using a binder with a high Tg (hereinafter, referred to as a high Tg binder) to improve the aspect ratio, and the printed electrode is fired, thereby obtaining the electrode with a high aspect ratio, improving contact between the substrate and the conductive electrode material, and improving cell efficiency. The present invention also relates to a manufacturing method thereof and to a solar cell.
