Optoelectronic systems are being used to an increasing extent in the manufacture of photovoltaic (PV) modules and are helping greatly to increase production efficiency. In particular, laser technology is proving its superiority in processes such as material removal, fusion, soldering, welding and drilling. Lasers have become indispensable tools, especially in the manufacture of thin-layer solar cells. Manufacturers are therefore profiting directly from the continuing positive trend in the photovoltaics industry: Trade associations and research institutes are predicting a growth rate of between 10 and 20 percent in 2011. LASER World of PHOTONICS 2011 will therefore also examine the area of photovoltaics manufacturing as part of the focus topic of “Green Photonics” from May 23 to 26, 2011.
