The use of lasers in the processing of solar cell structures has been known for many years both for c-Si and thin-film solar technologies.
In addition, several laser-processing techniques are currently being investigated for the production of new types of high performance silicon solar cells. There have also been research efforts on utilizing laser melting, laser annealing and laser texturing in the fabrication of solar cells.
Independent of the solar cell concept, lasers have always played a role in the de-velopment of new production processes. In some cases, there is a strong competitive situation with one or two alternative technol-ogies, but in many cases no other tool can compete with the speed and precision of the laser.
Laser processing has become a key technology for the industrial production of crystalline silicon solar cells reaching higher conversion efficiencies. Enhancements of the current solar cell tech-nology are achieved by using advanced ap-proaches like laser grooved front contacts or selective emitter structures.
The fundamental process of most laser struc-turing applications on solar cells is the direct laser-induced vaporization and melt ejection by nanosecond laser pulses.
There have also been research efforts on utilizing laser melting, laser annealing and laser texturing in the fabrication of solar cells. Recently, a number of manufacturers have been developing new generations of solar cells where they use laser ablation of dielectric layers to form selective emitters or passivated rear point contacts.

An established c-Si laser application is edge isolation. After manufacture of the active layer of the cell, a continuous edge creates a potential short circuit between the active and the back sides. To overcome this, green (532nm) or UV (355nm) nanosecond pulses from a Nd:YAG or Nd:Vanadate laser are used to scribe narrow grooves which are typically 30-50mm wide and 5-10mm deep …
