Laser process implementation has a considerable impact on the efficiency increase potential for crystalline silicon solar cells. Jonas & Redmann develops and manufactures automation solutions for the efficient loading and unloading of industrial laser systems.
In order to make the manufacture of solar cells a competitive business, a high level of automation in the production plants is essential. Efficient, fully automated linking of the individual process steps helps to significantly increase the output per hour.
Jonas & Redmann Wafer Inspection System - WIS is used for the fully automatic inspection of mono and poly crystalline silicon wafers. This system is modular and provides a high degree of flexibility. With on-the-fly inspection, wafers undergo quality checks in accordance with customer specifications. Using the primary host computer, the inspection criteria can be quickly and easily adjusted to the given requirements and saved in inspection formulas. The sorting of the wafers can be user-defined based on the chosen inspection criteria. For this purpose, the system enables the user to define a custom number of sorting classes depending on the configuration of the sorting area.
Jonas & Redmann Wafer Handling Diffusion - WHD is the result of our commitment to the continuing development of established technology and many years of experience with the aim of significantly increasing the productivity of the POCl3 diffusion process step. The system distinguishes itself in its ability to automate the series production of crystalline solar cells, mainly thanks to its highoutput, high uptime and compact space-saving design.
Jonas & Redmann Wet Inline Loading/Unloading is used for the loading and unloading of inline wet process systems, such as acid texturing, phosphor glass etching or wet isolating edges. The system is distinguished by its extremely gentle material handling with specially developed gripping devices as well as its high output and reliability. The wafer is positioned in the wet bench inflow without touching the edges. The system is available in various designs and allows for the automation of inline wet chemical systems from a wide range of manufacturers.
This system is used for the fully automated loading and unloading of silicon wafers from graphite process boats for processing in a batch PECVD system. The accurate position of the wafers in the graphite boats is essential to ensure the flawless electric contact with the wafer that serves as the basis for a stable PECVD process. For nearly a decade, Jonas & Redmann WHP has defined the state-of-the-art in production cluster anti reflective coating with PECVD direct plasma. The new generation of Jonas & Redmann Wafer Handling Plasma - WHP is the result of this continuous development: it can be modularly configured and therefore perfectly adjusted to suit the performance of the process cluster. It is this innovation which helps customers to achieve a dramatic increase in system productivity.
JRT Photovoltaics GmbH was formed by merging with the technology and market leader in flat bed screen process machines, THIEME. With the merger, Jonas & Redmann made significant steps towards process technology, and under the umbrella of the joint company can offer a complete metallization line from a single source.
Jonas & Redmann Cell Tester & Sorter - CTS is used for the fully automatic inspection and classification of completely processed mono- and polycrystalline silicon solar cells with as few handling steps as possible. The system is of modular configuration and provides a high degree of flexibility. The configuration of the inspection technology can be individually defined. The system allows any number of sorting classes depending on the sorter module.
