Samenvatting:
An environmental Life Cycle Assessment has been conducted for standard
and advanced production technologies for multicrystalline silicon module
production and new BOS concepts. It was found that the production route
based on Solsilc silicon feedstock and RGS wafer technology can yield
a 50% reduction of the environmental impacts in comparison with present-day
standard technology. Similar results were obtained for a process using
Bayer/Deutsche Solar feedstock material and EFG ribbon technology. New
BOS concepts can also help to reduce environmental impacts especially
if they allow the use of frameless modules. With such new technologies
life-cycle greenhouse gas emissions of PV systems in Southern-Europe
can be reduced to about 30 g/kWh and energy pay back time can be as
low as 1.2 years.
