Laser processes for solar cells

Laser processes play an increasingly important role in the fabrication of solar cells and modules. Thin film layer removal through glass substrates, edge isolation, via drilling for Metal Wrap Trough cells, module connection and separation are all vital processes done with the energy supplied by lasers. The material selectivity and localized processing are the driving forces behind this development. The use of short pulsed laser lasers with pulses in the region of femtosecond to picoseconds is crucial for the development of high quality thin film interconnection. This enables a one-step back-end serial interconnection approach instead of sequential scribing following every deposition step in the build-up of solar cells. This back-end approach may reduce manufacturing cost and increase panel efficiency thus being a vital process step in sophisticated solar cell manufacturing.
