摘要：
The invention relates to a photovoltaic cell, preferably a thin-film photovoltaic cell, having a substrate glass made of aluminosilicate glass, comprising a glass composition which has SiO
2 and Al
2 O
3 as well as the alkaline oxide Na
2 O and the alkaline earth oxides CaO, MgO, and BaO, and optionally further components, the glass composition containing 10 to 16 wt.-% Na
2 O, > 0 to 1 to 10 wt.-% BaO, and the ratio of CaO:MgO being in the range of 0.5 to 1.7. The aluminosilicate glass used according to the invention is crystallization stable because of the selected quotient of CaO/MgO and has a transformation temperature Tg > 580°C and a processing temperature VA
