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...

Functionalized silicon nanocrystals

BackgroundSilicon (Si) is an extraordinarily useful semiconductor, employed in integrated circuits, solar cells, and photodetectors; however, it exhibits no significant luminescence at room temperature because of its indirect band gap. Silicon nanocrystals (SiNCs), or quantum dots, on the other hand can be efficient light emitters, with emission wavelength...
