CHEMNITZ, Germany — The MicroDice™ OTF system by 3D-Micromac AG uses thermal laser separation (TLS) technology to split photovoltaic cells into half cells.
The use of half cells increases the average module power yield. Compared with laser scribing and cleaving approaches, TLS-cut cells show higher mechanical strength and better edge quality, with reduced handling costs.
The TLS process is based on thermal-induced mechanical stress, generated by a combination of laser heating and cooling.
The MicroDice OTF achieves a throughput of 3600 cells per hour. The optical setup relies on the same on-the-fly technology used in the company’s laser structuring tools for processing PERC (passivated emitter rear contact) cells. The continuous, automatic transport of the cells under the laser source results in nearly full-capacity utilization of the laser source. Stops for the positioning of individual cells have been eliminated. The fully automatic, 24/7 production system is offered as a standalone or inline unit.
