Corte de placas solares con láser : Estudio de modificaciones microestructurales

In photovoltaic solar cells manufacturing process, system breaks are produced. Recycling improves the material profitability. In this sense, manufacturing of components with non-straight shapes is not feasible using traditional methods. The processing of these materials through Nd-YAG laser, allows manufacturing with any geometric shape. This work shows a study of solar cells cutting process with laser. First to all, it is necessary to carry out a parameter optimization in order to make an accurate material cutting. The microstructure of the cutting area and possible microcompositional changes were studied by scanning electronic microscopy (SEM) and X-ray analysis (EDX).
