Electrochemical production of solar-grade silicon films from SiO₂

Background Silicon thin films are an important limitation for solar photovoltaic cells. Currently, manufacturing of these films are from single crystal silicon and a large amount of raw material is wasted. Single crystal silicon is not a cheap commodity. Thus, the sawing process used on single crystal silicon is costly not only from a manufacturing...
