Since the silver paste plays a major role in the mass production of silicon solar cells, this work has succeeded in optimizing the silver paste in 80–85 wt.% and optimizing its particle size in 1–1.5 μm spherical powder. As the firing temperature is increased, the growth trend of silver grain is improved.

The Cs 2 SnI 6 perovskite was adopted as the light absorber layer of lead-free perovskite solar cell for the first time due to its small bandgap of 1.48 eV and high absorption coefficient, showing a PCE of about 1% with a Voc of 0.51 V and a Jsc of 5.41 mA cm −2 after optimizing the perovskite film thickness.
The silver paste on the back side mainly plays the role of adhesion, and is mostly used on the backlit side of P-type cells. Therefore, the silver paste on the front side of photovoltaic panels requires a higher level of production process and electrical conductivity.
Photovoltaic silver paste is mainly composed of high-purity silver powder, glass powder, and organic raw materials, produced by mixing, rolling pulp, and other processes. Positive silver paste is a formula-based product; the precise ingredients affect the subsequent links, which in turn affect the silver powder.
