A photovoltaic cell, for example a thin-film photovoltaic cell, having a substrate glass made of aluminosilicate glass, has a glass composition which has SiOand AlOas well as the alkali metal oxide NaO and the alkaline earth oxides CaO, MgO, and BaO, and optionally further components. The glass composition includes 10 to 16 wt.-% NaO, &#x3e;0 to &#x3c;5 wt.-% CaO, and &#x3e;1 to 10 wt.-% BaO, and the ratio of CaO:MgO is in the range of 0.5 to 1.7. The aluminosilicate glass used is crystallization stable because of the selected quotient of CaO/MgO and has a transformation temperature &#x3e;580&#xb0; C. and a processing temperature &#x3c;1200&#xb0; C. Therefore, it represents a more thermally stable alternative to soda-lime glass. The aluminosilicate glass is used as a substrate glass, superstrate glass, and/or cover glass for a photovoltaic cells, for example for thin-film photovoltaic cells, in particular those based on semiconductor composite material, such as CdTe, CIS, or CIGS.

The invention relates to an alumino-silicate glass which has a thermal expansion coefficient in the range of 8 to 10&#xd7;10/K in a temperature range of 20 to 300&#xb0; C., a transformation temperature Tg in a range of 580&#xb0; C. to 640&#xb0; C., and a processing temperature VA in a range of 1065&#xb0; C. to 1140&#xb0; C. and which can therefore be used as an alternative for soda lime glasses. An object of the invention is also the use of the inventive glasses in applications where a high temperature stability of the glasses is advantageous, in particular as substrate glass, superstrate glass and/or cover glass in the field of semiconductor technology, preferably for Cd&#x2014;Te or for CIS or CIGS photovoltaic applications and for other applications in solar technology.
