Synthesis process of non-rare metal (Si and C) quantum dot photovoltaic material which can be used as next generation of solar cells was developed. In order to generate such quantum dot materials, new type of laser ablation process was developed. Core shell structured particles with silicon cores with diameter smaller than 10nm was successfully generated by combining laser technology with aerosol process. These core shell particles were then deposited on the solid substrate to generate quantum dot structured films.
