However, the expensive price of silver paste is one of the barriers to the production of low-cost solar cells. Therefore, the most focused target in photovoltaic research is the decreasing consumption of silver paste or substitute silver for other materials.
The performance of the front silver paste plays a significant role in the photoelectric conversion rate of solar cells. The silver paste printing performance determines the width of the front electrode sub−grid line of the solar cell and directly affects the light−receiving area of solar cells [ 10 ].
Silver paste used for the front electrodes of solar cells is one of the key materials used in the production of crystalline silicon solar cells [ 5 ].
The high sintering activity of the silver powder leads to the dissolution of the glass layer and increased silver deposition. Consequently, the paste exhibits excellent conductivity, low contact resistance of the silver electrode of 1.23 mΩ, high series resistance of the solar cell of 23.16%, and a photoelectric conversion efficiency of 23.16%.
