How can laser-processing be used to make high performance solar cells?

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.

Can lasers be used in the processing of solar cell structures?

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.

What are laser processes in PV cell manufacturing?

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.

Can laser annealing be used to make solar cells?

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.

How do solar cells work?

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. Others have been utilizing lasers to drill holes through the silicon wafers for emitter-wrap-through or metal-wrap-through back-contact solar cells.

Are Lasers a viable form of thermal treatment for thin-film based solar cells?

These advantages enable the lasers to find a viable form of thermal treatment in the processing of industry compatible CZTS thin-film, which is a promising material for producing low-cost non-toxic thin-film based solar cells (TFSC) [7,8] .
