Abstract: Utilization of a glass for photovoltaic applications, whereby the glass has a water content of <25 mMol/liter, for example >1 mMol/liter. The used glasses may have a transformation temperature Tg in an approximate range of >580° C., a processing temperature (“VA”) in the range of approximately 1150° C. and a thermal heat expansion coefficient in the range of approximately 7 to 11×10?6/K. These glasses may be used in a high temperature process without releasing semiconductor toxins such as iron, arsenic and boron, and are suitable for Cd—Te or for CIS or respectively CIGS photovoltaic applications since the processing ability/deposition compared to traditionally used soda lime glasses can occur at higher temperatures due to higher temperature stability.
