Researchers have proposed induced ablation as an alternative laser scribing technique to achieve highly selective film removal and steep wall scribes. Employing this approach for scribing CZTSe thin-film solar cells with an IR ps laser has improved removal quality, selectivity, and crater edge quality without the presence of defects .
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.
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 of the existing reports on solar cell cutting are focused on the laser wavelength, type, performance, and cutting parameters (depth of cut, speed, and direction of cut) to illustrate how to reduce the damage (hidden cracks, p-n junction leakage, and contamination) caused by laser cutting on solar cells [ 16, 17 ].
Solar energy is indispensable to tomorrow’s energy mix. To ensure photovoltaic systems are able to compete with conventional fossil fuels, production costs of PV modules must be reduced and the efficiency of solar cells increased. Laser technology plays a key role in the economical industrial-scale production of high-quality 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.
