Title
Noncontact laser soldering joins arrays of solar cells.
Abstract
The article discusses the development of a soldering system for silicon solar cells that uses a noncontact laser. The system was created by the Fraunhofer Institute for Laser Technology and passes a laser over a stringer while an infrared camera regulates the laser's power through temperature measurement, ensuring accurate soldering. The article discusses plans for a laser welding system for solar cells.
