Abstract

AbstractLasers as production tools offer several advantages, which are especially relevant for the production of solar cells. The contactless and localized nature of the energy deposition allows new processes, such as laser selective emitter doping, laser ablation of dielectric coatings and via drilling for back contact cell concepts. A critical factor is the selection of suitable laser sources and parameters in a manner that adapts the laser process to the requirements of the material, the process nature and the solar cell properties. In this paper three laser processes are investigated with the goal to identify the most suitable laser source
