Abstract
Abstract In an arrangement having a surface for accommodating photovoltaic cells which are adapted to be connected to a current collector or the like, in particular in the case of a roof skin which is stretched over frame members, the arrangement is formed in the manner of a net from cables and the photovoltaic cells are disposed at or between the junctions of the cables. The invention also includes the photovoltaic cells which are arranged floatingly at the flexible surface of the arrangement.
