5 FAQs about [Photovoltaic printed stencil]

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 stencil printing improve fine line print quality?

Higher efficiency is generally realized by optimizing the busbar design, printing finer lines or making adjustments to the silver paste. This paper examines the use of stencil printing instead of screen printing in order to achieve improved fine line print quality for greater efficiency.

What is the difference between a screen and a stencil?

In contrast to screens, the metal foil of a stencil is hardly deformed during the printing process, which leads to a better alignment precision and a significantly longer lifetime when handled adequately. Stencil-printed fingers usually show a significantly better uniformity (no “mesh mark” effect) and a high aspect ratio.

What is the difference between stencil and screen printed fingers?

The printed finger width ranges from 35.8 ± 2.3μm for 30μm stencil opening to 46.7 ± 3.4μm for 40μm screen opening which leads to an 0.5% abs increased metallized area on the front side of the screen printed fingers compared to the stencil printed fingers.

What is a double-layer stencil?

Double-layer stencils allow a combined printing of fingers and busbars using one printing form. Compared to single-layer stencils, a better edge homogeneity of the printed fingers can be achieved due to an optimal sealing between the soft emulsion along the finger channel edges and the textured silicon surface (see Section 3.2).
