Laser Technology Increases Efficiency Of Solar Cells
InnoLas Systems GmbH reports a healthy start to 2012 with a strong order book. At the end of last year the company 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 company says the efficiency of mono-silicon and poly-silicon cells can be increased by up to 0.5 percentage points.
InnoLas claims an outstanding throughput for this process step, so that one line can produce up to 100 MW cell power.
InnoLas sales director Alejandro Becker: "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."
