We optimise existing and develop new processing steps for industrial solar cells of today and tomorrow. Our focus is on crystalline silicon-wafer based technology and we work both with traditional poly silicon and novel solar grade silicon materials.
Our main objective is to further decrease the costs of electricity generation using Si-based photovoltaics. As a result, we want to promote the wider use of this technology.

ISC Konstanz cooperates with leading companies and research institutes of the PV-sector.

What we offer:

• Optimisation of existing and development of new processing steps and  equipment for the industrial production of solar cells with high efficiencies
• Development and testing of novel solar cell concepts
• Small-sample production of special as well as partially-processed solar cells applying customer-defined processing steps on our processing-equipment
• Loss-analyses of solar cells and modules
• Solar cell characterisation using our characterisation equipment and running simulations

We also develop and optimise single process steps for standard industrial solar cells:

- Wet-chemical processing (e.g. texturing, diffusion, contact formation)
- Diffusion engineering (selective emitter and local back surface field formation, lowly doped emitters, advanced gettering)
- Novel passivation approaches (SiC, SiCN, gradient layers, coloured solar cells for building integration)
-Improved mettalisation (fine-line printing, plating, paste development)

Our further foci are on advanced solar cell concepts and manufacturing, such as:

- N-type solar cells (front and read junction approaches)
- Structures with open rear contact (mono- and bifacial application)
- Rear-contacted devices (MWT, EWT, IBC)
- Devices adapted to light injection (0.01-10 suns)
- Development of prototypes with our industrial partners
