The Process of Silver Paste Application in Photovoltaic Cells

Silver paste plays a crucial role in the manufacturing of photovoltaic cells. It is used to create electrical contacts on the surface of the cells, allowing for the efficient collection and conduction of electricity produced by the cells. The application of silver paste involves a specific process to ensure proper functioning of the solar cells.

Application Process

The application of silver paste begins with forcing the paste through a patterned screen. This screen contains openings that correspond to the desired pattern of the metal contacts on the cell surface. When the paste is forced through the screen, it fills the gaps in the pattern, leaving a precise metal pattern on the surface of the cell.

Importance of Silver Paste

Silver paste is preferred for its high conductivity, which is essential for efficient electricity conduction within the solar cell. Additionally, silver is highly reflective, allowing it to enhance the absorption of sunlight by the cell. These properties make silver paste an ideal material for creating electrical contacts in photovoltaic cells.

Conclusion

The application of silver paste is a critical step in the manufacturing of photovoltaic cells. By following a precise process, manufacturers can ensure the proper formation of electrical contacts on the cell surface, leading to the efficient generation of electricity from sunlight.
