Topsil Photo Voltaic Float Zone (PV-FZ™) monocrystalline silicon wafers are recognised for their superior quality in the PV-industry. Float Zone technique is used for growing the moncrystals, resulting in wafers with efficiencies above 20%.
Topsil PV-FZ™ silicon has been developed to meet solar industry's material requirements and cost levels. The wafers support the development of stable, high efficiency and cost effective solar cells. They are characterised by the following parameters:
- High minority carrier bulk lifetime
- Low oxygen content
- Low resistivity variation
The PV-FZ™ silicon is available as n-type and p-type products, bulk resistivity targets in the range of 0.5-30 Ωcm, and diameters up to 150mm.
