German laser company, Jenoptik has expanded its solid-state disk laser product portfolio by introducing a new powerful infrared disk laser called JenLa disk IR70. The laser is suitable for latest technologies in the photovoltaic market such as emitter wrap-through and metal wrap-through (MWT).

Both EWT and MWT technologies enhance the electrical effectiveness of the solar cells. Through these technologies, the contacts are deployed on the backside of the solar cell instead of the front side to expand the surface of active cell, and eradicates part of the earlier contact tracks that shade sa portion of the active cell surface.
The JenLa disk IR70’s pulse lengths can be modified without adjusting the repetition rate, thus enabling maximum process parameters. The infrared disk laser, with maximum repetition rates of 100 kHz and pulse energy of 7 mJ, can be used in a number of applications that come under the range of infrared wavelength of 1,030 nm. This aspect makes the 65 W laser suitable for laser drilling of silicon wafers for manufacturing high-efficient solar cells with backside contacts.
The JenLa disk IR70 is also used for micro structuring and micro materials processing applications. Missouri-based company, RPMC Lasers distributes Jenoptik products in North America.
