Recent developments in the sapphire glass industry reported in the general press mean the possibility of combining Solar-Tectic LLC semiconductor sapphire technology with the new sapphire glass technologies. This past year Solar-Tectic LLC succeeded in depositing single crystal silicon on sapphire substrates below the softening point of soda-lime glass (600C). The results were confirmed by a pole figure, TEM, SEM, and XRD. Solar cells were also made from sapphire samples this past year using only several microns of silicon.
