Silicon Genesis (SiGen) has made a move towards what it deems as a replacement of the wire saw process with the production of solar wafers using its PolyMax system. SiGen has produced 85μm thick, 156 mm square kerf-free monocrystalline silicon wafers; Kerf being a material that is translated into saw dust and used in the sawing process.
“We believe the benefit of using kerf-free wafers will allow the PV industry to reach unsubsidized grid parity. The start up of our high volume manufacturing system is a key step towards achieving this goal,” said Francois Henley, CEO of SiGen.
SiGen will introduce its PolyMax production system at the 25th EU PVSEC in Valencia, Spain.
