This project is focussed on a study of wavelength-dependent effects and pulse-duration effects on laser scribing of polycrystalline thin-film PV materials. The materials studied here are CdTe, CI(G)S, SnO{sub 2}, ZnO, molybdenum and gold. This paper provides a summary of thresholds and optimum scribing energy densities for two types of Nd:YAG lasers, a 308 nm excimer laser, and a copper vapor laser. A comparison is presented of glass-side vs. film-side scribing. Discussion is also given of scribing of multilayer films such as ZnO/CIS/moly and gold/CdTe/SnO{sub 2}. {copyright} {ital 1997 American Institute of Physics.}
