Solar cells checked by high power diode laser line generator
There are already line lasers with short lines (450 watts, 12 times 0.1 square millimeter) serving as inexpensive standard solutions in the thermal processing of silicon, for example. The generators structuring AMOLED (active matrix organic light emitting diode) displays with 80mm long lines supply several kilowatts of power. This technology is designed to add to the changing energy policy: a line laser (40 watts of power, 808nm wavelength and 165mm line length) is able to scrutinise solar cells using the so-called photoluminescence spectroscopy.
