Faithful to our motto, “anticipate tomorrow”, as of today, we have filed the industrial patent for a new PV cell interconnection system.
Since 2017 our Italian Research and Development department has been working on Silk, a new generation of high-efficiency 12-busbar crystalline silicon modules. This range of products exploits the concentration effect of the cylindrical ribbons and the resulting increased current to ensure higher yield, even when solar irradiance is low.

The market’s interest in this new generation of modules has led us to invest in a project that will focus on production engineering. Our R&D team has aimed at maximising production capacity while increasing the soldering quality and accuracy.

The result is this new flexible stringer machine named Silk, designed to enhance the excellent performance of 12-busbar modules. This stringer works with cells from 5 to 12-busbars and can adapt to future busbarless cells applications.
The stringing process
The machine operates during the first PV module processing stage, which is also one of the most delicate as it determines the quality and durability of the finished product. The stringing process results in a string of soldered photovoltaic cells interconnected in series.
After a long period of testing, also in cooperation with spin-offs of the University of Padua, our Italian R&D department has filed an international patent covering this “equipment to electrically connect photovoltaic cells in series and the method of said equipment” and completed its construction.
Triple production capacity
This new fully automated production technology, equipped with high-speed pick and place robots, can string up to 3000 cells per hour, i.e. three times faster than today’s standard in the 12-busbar market.
High-speed pick and place robots.
Our innovative production technique, covered by industrial secrecy, has further improved module durability, as ribbons are welded in a more delicate, precise and uniform manner, thereby increasing yield and minimising the risk for microcracks and hot spots.
This stringer will be used in our new production plant in China, a 20,000 m2 factory that will count 200 employees.
