#03 Print百度文库nest
When depositing the wafers in the print nest, they are precisely placed. The wafer is affixed with the help of a vacuum on the interruption-free print nest, so that a precise printing is assured. The print nest is equipped with a paper support which ensures a consistent clean print nest surface. It is possible to optionally interconnect a paper check, which inspects the paper for contamination. After a screen changeover, the roll-to-roll paper support can be used as a test print substrate to avoid the usage of wafers for set-up. The paper feed/ transport guarantees a smooth wafer transport to the following stations.
Breakage control / breakage discharge Print control Buffer storage Automatic paste feed Weighing station Patented paper control Firing sunny-side-up MWT (Metal Wrap Through) Selektive Emitter Laser edge insulation
#02 Print station
The printing station is characterised by the smooth screen printing ensuring low wafer mechanical stress. The screen can be moved in cleaning position, so that the printing mechanism is easily accessible. Changing the screen and squeegee is rendered extremely simple and easy. The automatic screen positioning by means of a camera system ensures high precision and accuracy of printing. High throughput performance is attained through „authentic“ double usage. The printing station is suitable for future cell designs.
JRT–backed by two technological leaders
The independent JRT Photovoltaics combines the know-how and market experience of two strong partners: Jonas & Redmann and Thieme. The result is an optimal service spectrum in the sector of metallization and handling technologies for the partial coating of crystalline solar cells. Here, the highest quality standards, innovative technologies and the synergy of long-year experience come together in the respective core competencies.
BUT IN THE END THERE IS JUST ONE BECOMING ACCEPTED: THE JRT SYSTEM CONCEPT.
For the solar industry JRT is offering a standard-setting flexible system concept for the partial coating of silicon wafers by screen printing which ensures a high quality of print combined with minimum breakages and low tooling and maintenance times. For purposes of adaptation to requirements, JRT offers a number of other special features:
JRT–the system concept
The JRT metallization line consists of the Print Line and Test Line modules. On the following pages, you will be introduced to the JRT metallization line, step by step. You will be able to see for yourself just how unique it is.
Output data depend on the process parameters. The technical information is subject to change.

Regenerative energy generation is efficient, renewable, and environmentally friendly. The use of solar energy is continually increasing, as well as the number of suppliers of crystalline solar cells and the competitiveness of the related markets. The mission from JRT is to render the production of crystalline solar cells more economical, with greater process optimisation and cost efficiency.
#01 Control
The clear text indicator provides an optimum overview. Large displays, savable parameters including formulation management as well as the usage of the most modern SPC technology contribute to user friendliness. The system is equipped with a MES interface for the monitoring of quality-relevant parameters and a single wafer pursuit. A visualisation of the image processing as well as the system technology with condition analysis is integrated in the system concept.

JRT–the customer‘s objectives are our objectives
Our declared objective is to make our industrial partners more competitive through more efficient installations and services. The successive reduction in wafer thickness reduces the use of silicon, our processing and coating procedures increase throughput while cutting breakage rates, ensuring a high efficiency at low cost. Furthermore, we understand „leading technologies“ as a daily challenge to implement the requirements of our customers with passion and ambition. With many innovative new features and characteristics, reliability and quality, we are shaping the future for strong partnerships and successful customer relations.
