Conductive silver paste for front electrode of solar battery and preparation method of conductive silver paste

The invention discloses conductive silver paste for a front electrode of a solar battery. The conductive silver paste comprises the following ingredients by weight percentage: 70-90% of silver powder, 2-10% of glass powder and 5-20% of organic carrier. The invention further discloses a preparation method of the conductive silver paste for the front electrode of the solar battery. The conductive silver paste for the front electrode of the solar battery has good thixotropy; after silk-screen printing, the obtained front electrode of the solar battery is small in width and great in height, that is, an aspect ratio of an electrode grid line is high, so that the front lightproof area of the solar battery is small; and the solar battery has good performance.
