Abstract

Under processing condition that were the average power of 20 W, repetition frequency of 2 kHz, pulse width of 80 ns, spot diameter less than 20 m, cutting speed of 10 mm/s, we succeeded in making 300 m thick gold interconnectors for solar cell panels, by utilizing an optical fiber laser with high power density. These interconnectors could effectively prevent the oxidation corrosion from atomic oxygen in space, meanwhile reduce ohm-contact and series resistance of electrodes. Therefore, both the performance and stability of solar cell could be significantly improved.
