Innovative laser technology convinces PV manufacturers

InnoLas Systems GmbH starts the year 2012 with well filled order books. Just before Christmas the company based in Krailling (Munich), Germany received orders from two international manufacturers for production systems with a capacity of more than a Gigawatt. These systems support the innovative Laser Doped Selective Emitter (LDSE) technology. This additional process step uses the laser to diffuse dopants into the silicon underneath the later added metal contacts. Using this process, the efficiency of mono-silicon and poly-silicon cells can be increased by up to 0.5 percentage points.

The InnoLas systems achieve an outstanding throughput for this process step, so that one line can produce up to 100 MW cell power.

InnoLas sales director Alejandro Becker said: “This higher efficiency is a major selling point for the PV manufacturers. Therefore we see a strong interest worldwide to upgrade existing production lines with LDSE. As a leading supplier for systems using laser technology we benefit from this trend very strongly.”
