Comparative study of nanosecond and picosecond laser pattering of thin film for photovoltaic solar modules based on a-Si:H

Research Areas
  • Magnetic materials

The monolithical series connection of silicon thin-film solar cells modules performed by laser scribing plays a very important role in the entire production of these devices. Therefore it is necessary to perform a good characterization of the laser process, along with the assessment of different laser sources. The usual process is based on a configuration of modules where the glass is essential as transparent ubstrate. In addition, a change of wavelength in the employed laser sources is sometimes needed due to the various types of materials making up the multilayer structure of the device. The aim of this work is to characterize the laser monolithic interconnection process accomplished by using nanosecond and picosecond laser sources from the film side with the purpose of evaluating these laser sources to improve the process. The use of ultrafast sources, such as picoseconds lasers, gives the possibility to consider materials and substrates different than the currently used, making the process more efficient and easier to implement in production lines. This approach with nanosecond and picosecond laser sources working from the film side offers no restriction in the choice of materials which make up the devices and the possibility to opt for an opaque substrate.
