Influence of pulsed Nd:YAG laser oscillation energy on silicon wafer texturing for enhanced absorption in photovoltaic cells

The influence of the Nd:YAG laser's oscillation energy on creating textured surfaces on silicon wafers is investigated in this study. The silicon wafer surfaces were directly ablated by a pulsed Nd:YAG laser beam to create the texturing, which was then examined using UV�Vis spectroscopy, AFM an...
