Robot-guided edge insulation for thin-film solar cells

摘要

Device for removing layers on glass by means of laser radiation in a thin-film solar cell, in particular for producing an insulating edge, in which the laser generates short pulses by switching the resonator, and in which the focal point of the laser is used to produce focal spots on the layer which are produced by adjusting devices be strung together, so that a surface removal is carried out in that the laser has as an active medium a neodymium-doped crystal which is pumped by laser diodes, the actuator is a two-axis galvanometer scanner, as commonly used in laser marking, and Laser and scanner are constructed as compact stationary unit.
