Figure 1From: Laser irradiation of ZnO:Al/Ag/ZnO:Al multilayers for electrical isolation in thin film photovoltaicsTypical interconnect scheme of an α-Si:H module in superstrate configuration. P1, P2 and P3 indicate the different patterning steps. P1 is performed using an infrared laser to remove the front TCO. P2 and P3 use a green laser to cut the Si solar absorber layer and the rear electrode, respectively.Back to article page
