Design and development of an automated laser processing system for photovoltaic applications

摘要

To reduce manufacturing costs and to improve electrical efficiency of solar cells are top priorities of the whole photovoltaic (PV) industry. The success of laser processing techniques in the integrated circuits industry indicates that such techniques could also be adapted in the PV industry. In this paper, we presented an automated laser processing system which was specially designed and developed for manufacturing of high efficiency solar cells. This system is modulized and can be easily modified for different laser applications for solar cells, such as laser doping, laser drilling, laser ablation and laser scribing.
