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.
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.
Laser technology plays a key role in the economical industrial-scale production of high-quality solar cells. Fraunhofer ILT develops industrial laser processes and the requisite mechanical components for a cost-effective solar cell manufacturing process with high process efficiencies.
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.
Using ns lasers may noticeably decrease the efficiency of the solar thin films, and ps and fs lasers have demonstrated much less efficiency drop in thin film solar cells [116, 128]. Furthermore, it must be mentioned that laser-type selection depends on the type of scribing and the film material to be removed.
Overall, the use of nanomaterials in thin film solar cell technology shows promise for enhancing cell performance. Laser scribing is a highly beneficial tool in the fabrication of thin-film solar cells, which typically consist of multiple layers of materials deposited on a substrate.
