Increasing throughput and high-uptime are key demands for PV module assembly. Reducing cell breakage rates and the ability to be upgraded tabbing and stringing tools to ever increasing busbar count means flexibility and serviceability of tools is required. 

Solution

The J.v.G. Thoma Stringer uses the newly developed Endless String Technology that is said to enable the stringer to reach up to 1,300 cells/h with a very high precision of ribbon alignment with an option handle 2.600 cells/h. Compared to other high end stringers on the market, the price per speed (cells / h) is very competitive, according to the company. The tool also provides less tension in the cell making less stress, resulting in a reduction in the cell breakage rate. The DESERT+ soldering solution we can process cells down to 120 micron thickness.

Applications

Tabbing and stringing of all types of solar cells.

Platform

The J.v.G. Thoma Stringer is designed to be low maintenance and have ease of operation. The new model has been thoughtfully designed so that it can be easily repaired with compatible replacement parts – even from suppliers other than J.v.G. Thoma. It is also possible to upgrade to new technologies when needed – giving the model a longer working life when migrating to new multiple busbar configurations.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
