6 FAQs about [Stencils used for printing photovoltaic cells]

What is PV cell inkjet printing?

Inkjet printing is a method used in PV cell manufacturing for depositing metal paste directly onto the surface of the cell through very small openings of a highly efficient, parallel print head. It offers a contactless, maskless printing alternative to conventional screen printing and stencil printing.

Can a stencil printing process improve a conventional screen printing technique?

In this study conducted by ISFH, a stencil printing process was implemented to evaluate possible improvements versus the conventional screen printing approach. Analysis revealed that the screen printing technique tends to produce solar cell fingers that have a wave-like shape along the finger direction.

Can flexographic printing be used for solar cell metallization?

These activities gathered a new momentum in the early 2010 years, when several research groups presented promising results of feasibility studies using flexographic printing, 370 - 372 rotary screen printing, 373 and gravure printing 369 for solar cell metallization.

What technologies are used to metallize silicon solar cells?

Beside screen printing, multi-nozzle dispensing, and rotary printing, further printing and coating technologies to apply the front and/or rear side metallization of silicon solar cells have been investigated in the last decades. Several studies investigated the application of the front side grid using inkjet technology.

Can flatbed screen printing be used for metallization of solar cells?

Sebastian Tepner and Andreas Lorenz contributed equally to this work. This paper presents a comprehensive overview on printing technologies for metallization of solar cells. Throughout the last 30 years, flatbed screen printing has established itself as the predominant metallization process for the mass production of silicon solar cells.

How many fingers can be used to print solar cells?

Various stencil foils with 25μm, 30μm and 40μm finger apertures were used to print three groups of solar cells. The finger number range is between 101 fingers for 40μm, 124 fingers for 30μm and 134 fingers for 25μm. Simultaneously, one group of cells was printed using 30μm apertures and a polymer squeegee.
