High Throughput Processing for Photovoltaics
Our group performs research in
- Process and Materials development for 3rd generation photovoltaics
- Continuous combinatorial methods for solution processed semiconductors
- Fundamental understanding of microstructure development during drying of thin films
- Continous characterization methods and process control
- „Lab-to-Fab“ device and process scale-up
Printing and coating of solution processed semiconductors has an outstanding potential for increasing the throughput and decreasing the cost of solar. The development of microstructure during drying and curing is outstandingly important for the performance of printed solar cells. In our team we investigate the effect of processing conditions and ink composition on efficiency utilizing methods that are comparable to those used in large scale production lines. We specicalize in combinatorial methods on continuous coating equipment in order to decrease the "Lab-to-Fab" transfer time.

Our Vision
is to develop disruptive technologies to revolutionize the way solar technology is manufactured and utilized. We develop high throughput processing techniques that make it possible to screen many material combinations and process parameters in parallel.
Printing is the most effective means to cover large areas with functionality. This is a manufacturing paradigm shift with the potential to drive solar power generation to ultra-low costs.
Our Infrastructure
is custom designed for the printing and coating of solution processable semiconductors. It provides a maximum flexibility with regards to substrate, material and process for the printing of solar modules. This includes equipment for process development, material evaluation, module manu-facturing:
- Fully equipped chemical lab with clean room capabilities and semiconductor grade materials storage and handling
- State of the art printing (ink-jet, screen, flexo) and coating lab for film deposition with nm precision in z-direction on rigid and flexible substrates
- Fully automated multi-head R2R printing and coating line for processing of func-tional electronic, opto-electronic and dielectric materials up to 40 cm web-width
- Multiple galvo-head equipped batch and R2R capable laser systems (ns, fs) for patterning of single- and multi-layer stacks with nm precision in z direction and micrometer lateral resolution
- Backend-Lab for contacting, encapsula-tion and packaging of solar modules
- Accredited electrical characterization lab for test structures, solar cells and PV-modules
- Non-destructive imaging lab with spec-troscopic and hyperspectral imaging and scanning methods (Raman, FTIR, PL, EL, Thermography, AFM, SEM)
- Accelerated Lifetime testing with variable temperatures (up to 1000 C, illumination (up to 500 suns) and atmospheres (con-trolled levels of humidity, O2, or other gases)
