Laser Metallization And Doping For Silicon Carbide Diode Fabrication And Endotaxy
… overcoming some challenges in metallization and doping during the fabrication of silicon carbide devices, a novel laser-based process is provided to direct metallize the surface of silicon carbide without metal deposition and dope in silicon carbide without high temperature annealing, as an …

Femtosecond-laser irradiation as a platform for tailoring the optoelectronic properties of silicon
… silicon allows for facile n-type and p-type doping, has a naturally passivating surface oxide, and long minority carrier lifetimes. The major drawback of silicon is that it has an indirect band gap at 1.1 eV. It is therefore a poor light absorber and is naturally transparent to light in the …

Pulsed Laser Dielectric Ablation for Copper-plated Silicon Solar Cells
… solar cell manufacturing. However, concerns of laser-induced damage with carrier recombination and plated metal adhesion have contributed to a low market fraction of Cu-plated modules. This thesis aimed to further understand the contact formation process using light-induced plating (LIP) on …

Applications of Spectrally-Resolved Photoluminescence in Silicon Photovoltaics
… also demonstrates that the damage induced by laser doping is related to dislocations, since its deep-level luminescence spectrum has similar properties to those emitted from dislocations in multicrystalline silicon wafers. The interface between the laser-doped and un-doped regions is found to …
