ISFH-SolarTeC: Industrial process tools for silicon photovoltaics

At ISFH SolarTeC, we process silicon solar cells in a production-oriented environment using industry-standard equipment. At the heart of this infrastructure is the 800 m² technology center, which houses equipment for wet chemistry, diffusion, oxidation, PECVD coating, screen printing metallization and module production. The technology center is complemented by a laboratory for laser processes.

At ISFH, we take an industry-oriented approach to developing new technologies that are ideally suited as drop-ins or add-ons for today's industrial mainstream. Current examples are passivating "Poly-Si-on-Oxide" (POLO) contacts and tandem solar cell concepts. This is achieved through close cooperation between all working groups in the photovoltaics department.

A particular strength of the SolarTeC at ISFH is its flexibility. We have many years of experience in comparing the processes and systems of our partners with our reference processes and systems at the SolarTeC using cross-processing. This offers our partners the opportunity to evaluate specific materials and individual process steps or to develop alternative solar cell and PV module concepts together with us.
