An apparatus and processes for large scale inline manufacturing of CdTe photovoltaic modules in which all steps, including rapid substrate heating, deposition of CdS, deposition of CdTe, CdCl2 treatment, and ohmic contact formation, are performed within a single vacuum boundary at modest vacuum pressures. A p+ ohmic contact region is formed by subliming a metal salt onto the CdTe layer. A back electrode is formed by way of a low cost spray process, and module scribing is performed by means of abrasive blasting or mechanical brushing through a mask. The vacuum process apparatus facilitates selective heating of substrates and films, exposure of substrates and films to vapor with minimal vapor leakage, deposition of thin films onto a substrate, and stripping thin films from a substrate. A substrate transport apparatus permits the movement of substrates into and out of vacuum during the thin film deposition processes, while preventing the collection of coatings on the substrate transport apparatus itself.

A series of laser pulses in a pulse train, each pulse with a predetermined temporal power shape, scribes a line in a thin film of material on a substrate. The predetermined temporal pulse shape has a fast risetime and fast falltime and a pulse length between 10% power points of less than 10 ns. Scribing a line in the thin film is achieved by placing the series of laser pulse spots on the line to be scribed such that there is some overlapping area between adjacent laser pulse spots along the line. The use of a series of laser pulses with the predetermined pulse shape to scribe a line in the thin film results in a better quality and cleaner scribing process compared to that achieved with a conventional pulse shape.
