Fine line screen printing for solar cell metallization is facing the increasingly difficult challenge of further decreasing the printed finger width to increase cell efficiency and reduce.
Screen-printing is a way of depositing a material (e.g., paste) on a surface according to a pattern formed in a screen comprising a network of meshed wires or strands. The pattern is formed in a polymer, called an emulsion, which is sensitive to light. When the screen is irradiated according to the pattern, the irradiated emulsion hardens and .
In photovoltaic applications, screen-printing is primarily employed in printing patterned Ag electrodes for crystalline-silicon photovoltaic cells (c-Si PVs), and then in printing mesoporous TiO 2 layer for dye-sensitized solar cells (DSSCs).
Printing layers that are nanometres to micrometres thick — uniformly and without pinholes, and over many square metres — is difficult. The electronics industry commonly uses screen-printing.

6 FAQs about [Is screen printing of photovoltaic panels difficult ]
How is screen printing used in photovoltaic solar cells?
Screen printing is also the most commonly and conventionally used printing process throughout the manufacture of photovoltaic solar cells. In fact, over 90% of all crystalline silicon modules are manufactured using screen printing, and about 60% of flexible thin film modules use screen printing in the manufacturing process ( Brenner, 2010 ).
Can solar cells be made using screen printing?
Screen printing has been used most prevalently in the printing process to make solar cells, but some companies have used the offset web press type methods to put material onto foil; they also have created solar cells with inkjet printing.
What are screen-printed solar cells?
Screen-printed solar cells were first developed in the 1970's. As such, they are the best established, most mature solar cell fabrication technology, and screen-printed solar cells currently dominate the market for terrestrial photovoltaic modules. The key advantage of screen-printing is the relative simplicity of the process.
Are screen-printed solar cells better than silicon solar cells?
The screen-printed PSCs with a porous structure can offer improved resistance to adverse environmental factors such as humidity, heat, and UV rays, achieving long-term light stability for thousands of hours. However, it is still difficult to compete with current silicon solar cells.
What is fine line screen printing for solar cell metallization?
Fine line screen printing for solar cell metallization is one of the most critical steps in the entire production chain of solar cells, facing the challenge of providing a conductive grid with a minimum amount of resource consumption at an ever increasing demand for higher production speeds.
