Elevate your production efficiency in solar cell manufacturing with the F-Theta lens JENar™ APTAline™ 429-515…540-339 AL
High precision solar cell scribing
Laser processing plays a crucial role in the manufacturing of thin-film solar cells, particularly for scribing cell interconnects and isolating module edges. Advanced optical components, such as Jenoptik’s F-Theta lenses, facilitate the creation of finer, smaller, and denser patterns on solar cells. These lenses are vital for consistently achieving high-precision results in various tasks, including laser structuring, soldering, and welding. For many applications, the use of ultra-short pulse lasers is essential, and the F-Theta objective must be capable of maintaining performance over the long term.
Key considerations for high-end laser systems:
- Substrate protection: Ensuring the integrity of the substrate and underlying layers is essential, especially for sensitive structures under 100 nanometers.
- Quality management: Effectively managing particle residue, thermal effects, and edge burr formation is crucial for maintaining high-quality results.
- Optimized process parameters: Careful consideration of gas atmosphere, pulse shaping, and post-processing techniques enhances overall quality. Utilizing hybrid processes like thermochemical ablation can effectively address specific challenges in structuring materials such as Indium Tin Oxide (ITO).
