- Abstract
Taking into account the absorption spectra of the hybrid-film (i.e., molybdenum (P1), copper indium gallium selenide (CIGS)/CdS/i-ZnO (P2), and AZO/CIGS/CdS/i-ZnO (P3)) layers of CIGS-based solar cells, we investigate the hybrid films of CIGS-based solar cells. P1, P2, and P3 isolated layer scribing is performed using infrared (1064 nm) and ultraviolet (355 nm) laser systems. The effects of different lasers on the P1, P2, and P3 isolated layers are discussed in terms of the scribing width and depth, bottom residuals, and edge debris. Subsequently, through energy-dispersive spectrometry and three-dimensional confocal laser scanning microscopy, we obtain the optimal laser process parameters. The experimental results obtained using nanosecond lasers are similar to those obtained using femto- and picosecond lasers in the literature.
