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.
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.
Most laser-based silicon solar cell processing requires silicon melting or ablation. For example, the silicon melting is required in the laser doping process to allow the dopants to diffuse into the silicon , , , and the silicon ablation is required in the laser microtexturing , and laser edge isolation , .
Summary and Outlook Laser processes efficiently perform important steps in PV cell manufacturing. Laser systems are proven in indus-trial production with lasers used for patterning and edge isolation for all thin-film PV technologies and for edge isolation scribing, grooving, contact vias and emitter dop-ing for c-Si technologies.
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.
Laser processing has a long history in the manufacturing of solar cells since most thin-film photovoltaic modules have been manufactured using laser scribing for more than thirty years.
