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.

Do rotary screen printed solar cells increase throughput?

The PERC solar cells obtain a mean conversion efficiency of η = 21.6 %. Furthermore, we present actual results regarding rotary screen printed front side metallization – a highly promising approach to increase throughput significantly. Using this technology, PERC solar cells are metallized at a printing speed of = 333 mm/s.

How fast are PERC solar cells metallized?

Using this technology, PERC solar cells are metallized at a printing speed of = 333 mm/s. A mean finger width wf = 47 μm and a mean finger height of hf = 13 μm is obtained. Keywords: Solar cell metallization, flatbed screen printing, knotless screens, rotary screen printing

Why is flatbed screen printing used in metallization of Si-solar cells?

1. Introduction Flatbed screen printing is the process of choice for the metallization of Si-solar cells with over 95 % market share because of it’s reliable and low cost production capabilities [ 1 ].

Are screen-printing PSCs a viable option for commercialization of photovoltaic systems?

This review highlights the significance of developing low-cost, efficient, and large-scale PSCs based on screen-printing technology, which opens up new avenues for promoting the practical commercialization of PSCs. With up to 26.1% of PCE, third-generation PSCs are highly competitive in the photovoltaic field.

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.
