<p><P>PROBLEM TO BE SOLVED: To improve a photovoltaic device having a condenser optics from a point of long term stability. <P>SOLUTION: The photovoltaic device includes at least one solar cell (7) and the condenser optics. The condenser optics includes: at least one first light incidence side focusing optical element (3); and at least one second optical element (5) which is arranged downstream of the first light incidence side focusing optical element, and which is arranged upstream of a solar cell (7) on which bundled solar radiation pours via the first optical element (3), at active position of a photovoltaic device (1). The second optical element (5) includes solarization-stabilized silicate glass. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
