Solar cell maker to develop manufacturing processes for removing backside passivation on its PERC cells.
With Hanwha Q CELLS, 3D-Micromac AG could win one of the leading global photovoltaic companies as a customer for its microSTRUCT OTF laser system. The system creates a selective opening of backside passivated multi- and monocrystalline solar cells, thereby achieving a throughput of 3,600 wafers an hour.
For this purpose, 3D-Micromac makes use of an innovative on-the-fly technology. The laser processing is realized during the continuous transport of the cells under the laser source, whereby the relative motion of the cells is automatically compensated for. Stops for the positioning of the individual cells are completely eliminated. The handling of the solar wafers is contactless.
The wafer surface thus remains unaffected. This ensures a gentle and frictionless transport of the wafers, cell breakage or micro cracks are avoided and a higher yield is achieved. The continual movement of the conveyor belt results in an almost 100-percent capacity utilization of the laser source.
“We are delighted that Hanwha Q CELLS will further develop its Q.ANTUM cell technology manufacturing processes (PERC process) using 3D-Micromac equipment. This shows that our strategy of supporting cell manufacturers with our process know-how in the implementation and development of new cell technologies is paying off,” states Tino Petsch, 3D-Micromac CEO.
“The microSTRUCT OTF has been consistently designed for productivity, performance and cost efficiency. This is reflected, for example, by the number of customer projects we are currently dealing with. Moreover, following the successfully concluded qualification phase of our laser process, we are hopeful for follow-up orders from Hanwha Q CELLS” according to Petsch.
