New developments: SECOND WIND FOR MULTI

Developed by TESYS in collaboration with PILLAR GROUP ingot manufacturing experts

Compatible with the most of directional solidification furnaces installed in previous years Available since 2011

The solution is unique and doesn’t have any analog all over the market Reliable and proven in mass multi Si ingot production Over 20 installations in operation

Increases output of waferable material Brings ingot manufacturing cost down significantly Fully automated control over the process

New developments: SECOND WIND FOR MULTI

INDUCTION MELTING IN COLD CRUCIBLE (IMCC)

Advantages of IMCC: �  much higher growth rate and productivity vs DS method �  no need for expensive quartz crucible and graphite hot zone �  ensuring homogenous distribution of resistivity along the ingot �  no contaminations from quartz crucible and nitride coating, metals, silicon carbide, oxygen etc.

Developed by TESYS in collaboration with PILLAR GROUP ingot manufacturing experts Pilot furnace in operation at TESYS facility Pre-serial furnace under construction

INDUCTION MELTING IN COLD CRUCIBLE (IMCC)

Output >18MT per month

�  Solar cells manufactured in an

industriall production line on IMCC wafers

�  The obtained efficiency of trial lots reached 16.3% on average.
