Abstract

Currently, silicon based photovoltaic devices are used as efficient solar collectors. The novel features of Si nanoparticles, such as the ability to tune the band gap as a function of size, make it a useful system to study. Our aim is to develop inorganic/organic hybrid silicon based nanoparticles to be investigated for their use in photovoltaic devices. A comparison study will be conducted between the solution reaction using Na 4Si 4 and NH 4Br versus reduction of SiCl 4 to produce hydrogen terminated silicon nanoparticles. These nanoparticles will then be capped via hydrosilylation with octene, styrene, and anisole. The yields, optical activity, and surface conjugation will be compared. The resulting nanoparticles will be characterized by power XRD, TEM, UV-Vis and fluorescence spectroscopies, and NMR.
