Roth & Rau invests in highly efficient solar cell technology 

Hohenstein-Ernstthal, 21 May 2008 – Roth & Rau AG has concluded a
development agreement with the University of Neuchâtel in Switzerland. In a
three-year program, equipment and technologies used in the production of
highly efficient crystalline silicon solar cells are to be developed with
the university’s Institute of Microtechnology (IMT). Roth & Rau AG plans to
invest around Euro 14 million in the project during the next three years.
This cooperation with one of the leading institutes in the field of
semiconductor solar cells will thus secure the company’s access to major
key technologies in the field of crystalline silicon solar cells. Roth &
Rau Switzerland AG, a Swiss subsidiary founded at the beginning of April
and based in Neuchâtel, will take over the contract research for Roth & Rau
AG within the framework of this cooperation.
