Reel-to-reel system for photovoltaics


A new turnkey reel-to-reel system from Rofin-Baasel (Daventry, Northamptonshire, UK) is targeted at the production of flexible photovoltaic products. This system has been designed to incorporate multiple laser sources, which can be used to perform several different processing tasks on Si, µSi, GIGS and organic cells, all within a single machine.

Built upon a substantial granite base, the system incorporates high-speed, high-precision motorized axes to drive vibration-proof optics when the system is being used in the step-and-repeat mode.

For on-the-fly applications, beam positioning is achieved using fast and precise galvo scanning heads. A fully integrated vision system enables precise alignment with fiducials and also enables automated inspection tasks to be carried out within the machine.
