摘要：
The present invention relates to a solar cell comprising a double tube composed of two glass tubes differing in the diameter and a photovoltaic conversion layer formed between the two glass tubes, the double tube being sealed at both ends of a part in which the photovoltaic conversion layer is formed, wherein at least one of the two glass tubes is composed of a glass comprising, in mass% based on the oxides, from 60 to 70% of SiO 2 , from 4 to 10% of Al 2 O 3 , from 0 to 3% of B 2 O 3 , from 0 to 4% of MgO, from 2 to 9% of CnO, from 1 to 10% of SrO, from 0 to 2% of BaO, from 10 to 16% of Na 2 O, from 0 to 5% of K 2 O, from 0 to 2% of ZrO 2 and from 0 to 2% of CeO 2 .
