HeraSol Application Center

Understanding customer needs means knowing their requirements. Therefore, we have application centers all over the world:
• Americas: West Conshohocken, PA, USA
• Europe: Hanau, Germany
• Asia: Shanghai
• Asia: Taiwan
• Asia: Singapore
Singapore represents our newest facility, which opened in the summer of 2011.
By understanding the applications of our customers, it helps us in solving their problems. Our new applications centers, with on-site production, enable us to process customer specific SI wafers, from the metallization of the wafer, to the performance analysis of the finished cell. Our experiments and analyses help us gain new insights in paste design, and those experiences provide benefits to our customers.
Over 40 years of experience in screen printing, new metallization techniques and a thorough knowledge in glass and precious metals processing form a solid base for our ability to optimize our pastes to meet our customer’s requirements. Our well-trained engineering staff conducts experiments in our application centers or at our customer’s site. Our application centers offer a facility for research, development and technical service that offer solutions that are transferable to large scale production. At some of our sites, the application center and production facility are collocated in order to allow rapid technology transfer.
The following equipment is available at our HeraSol application centers for the development and testing of our customer’s products:
