Abstract
Abstract Transparent pane for vehicles, in particular, a transparent cover for sliding roofs, lifting roofs and the like, with a transparent outer layer and a solar laminate lying flat against the inside of this outer layer. The active part of the solar laminate is formed of a first subsection lying in the outer edge area of the pane which is made of crystalline semiconductor material, and a second subsection that is made of an amorphous semiconductor material.
