The investigation and successful application of novel feedstock materials (n-type Si, solar grade Si), cell concepts and processing technologies depends on profound understanding of material and device physics.

We therefore apply a wide range of testing and characterisation methods such as:

• Evaluation of silicon feedstock by characterisation of solar cells produced thereof using variable processing steps
• Development and testing on novel processing tools
• Loss analysis of solar cells
• Degradation tests and cell stabilisation
• Development of new characterisation -method and -equipment
• Small-series production of special as well as partically-processed solar cells for experimental purposes, applying customer-defined processing steps
