INER opts for second Aixtron AIX 2800G4 system on route to 45% efficient Ge/III-V solar cells

Aixtron AG of Aachen, Germany says it received a follow-up order for an AIX 2800G4 Planetary Reactor system from Taiwan’s Institute of Nuclear Energy Research (INER) in the first quarter of 2009. The system will be delivered to INER in the second quarter, where it will be used for the MOCVD growth of germanium/III-V-based solar cells. Both reactors will provide materials for the High Concentration Photovoltaic (HCPV) Research Program.

INER has been developing III-V solar technology for several years, and says that in collaboration with other companies it has already built a working prototype cell with an energy conversion efficiency of over 35%. Furthermore, the institute adds that it is now accumulating the epitaxy manufacturing capabilities required for production of solar cells that will have energy conversion efficiencies of 45%.

“Thanks to the approval of a second MOCVD equipment budget, we are in position to acquire a second Aixtron AIX 2800G4 system, which will allow us to separate development from pilot manufacturing,” said Dr Cherng-Tsong Kuo, leader of the High Concentration Photovoltaic System Research and Development Project.

As with INER’s first AIX 2800G4, the latest system will have a 15x4 inch wafer configuration with options to utilize up to 8 inch wafers.
