Laser doping technique using continuous wave laser in multi-crystalline silicon solar cell process

In the fabrication of silicon solar cells process, laser doping (LD) technique is recently gathering many attentions because of its advantages such as be operated at room temperature and in the atmosphere. In this study, we tried to apply laser doping method for the emitter formation in multi-crystalline silicon solar cell. As the result, enough photovoltaic properties were achieved by illuminated I–V measurements. In addition, evaluation by EL imaging technique was verified that LD technique can be applied to fabricate multi-crystalline silicon solar cells.
