Solsol
founder Johannes Rostan has over eight years of experience in solar cell technology and engineering.
He is a specialist in crystalline-silicon as well as CIGS technology and holder of multiple patents.
Prior to founding Solsol, he was technical director of the ilangaPower project, where he planned a crystalline-silicon
solar cell factory in South Africa which will commence production soon.
After graduation, Johannes Rostan joined centrotherm photovoltaics technology GmbH as the coordinator for new
process technologies. In his doctor thesis Johannes Rostan did leading-edge research on amorphous silicon /
crystalline silicon hetero-structures at the Institute of Physical Electronics (ipe) at the University of
Stuttgart and was involved in multiple c-Si and CIGS research projects.

Dr.Stephan
Wansleben -
Manager Business Development |
|
|
Stephan Wansleben is involved in photovoltaics since 1998, when his company Qtec supplied
the vision inspection technology to the first production line of Schott Solar in Alzenau, Germany.
The world-wide popular series of solar cell/wafer inspection systems of ICOS were developed and introduced while
he was General Manager of ICOS Visions Systems GmbH. GPinspect GmbH, today a very prominent supplier of vision inspection
technology was co-founded by Stephan Wansleben in 2008.
Stephan Wansleben is leading the ilangaPower project which will soon launch the first solar cell factory in South Africa.
Stephan Wansleben is a graduate of Cologne University in mathematical high-energy physics. He continued his academic
career in theoretical solid state physics and applied mathematics at the University of Georgia, USA.

Philipp
Donn -
Technology assistant
|
|
|
Philipp Donn is concluding his education in Electrical Engineering at the University of Stuttgart. We are proud that he selected Solsol for his industrial internship.
During his studies he specialised in high efficiency mono-crystalline silicon solar cells, and in particular in the characterisation and simulation of thin film coatings for anti-reflexion layers.
One focus of his research is new coating materials for minimising reflexion losses.
