Photovoltaic screen printing stencil damage

Why is metallization of silicon solar cells still dominated by flatbed screen printing?

Today’s metallization of Silicon solar cells is still dominated by flatbed screen printing 1 mainly because of its reliable and cost-effective production capabilities.

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.

Is screen printing a success story for Si-solar cell metallization?

Over the last 15 years, screen printing of Ag-pastes for Si-solar cell metallization has become a success story by decreasing the printed electrode width from ≈120 µm in 2007 reported by Mette toward only 20 µm reported by Tepner et al. in 2020.

Is there a scaling problem for fine line screen printing?

This circumstance reveals a fundamental scaling problem for fine line screen printing in the upcoming years as all efforts are concentrated on printing smaller structures at an increasing process speed.

Is screen-printing a viable method for scalable fabrication of PSCs?

However, the best-performing device with an area of 1 cm 2 exhibits PCE exceeding 18% by the screen-printing method, whereas only 12.52% was achieved with the spin-coating process (Fig. 4c), indicating the potential for scalable fabrication of PSCs.
