Abstract: Mobile radio reception, in particular in motor vehicles, has the disadvantage in comparison to geographically fixed home reception, that line of sight contact with the transmitter rarely exists and the signal strength near the ground is significantly smaller than the signal strength for roof-top antennas. For minimizing these disturbances, antenna diversity systems were developed. A practical problem in the realization of antenna diversity systems is comprised therein, that the diversity circuits do not support a targeted selection of individual antennas so that the individual antennas following installation can be tested for their functionality.

Abstract: The invention relates to a body part of a vehicle provided with a support and with a transparent covering layer. A thin-film solar cell is applied to said support. The support, together with the thin-film solar cell, is covered by the transparent covering layer. The transparent covering layer consists of a paint layer, particularly a clear varnish layer. The thin-film solar cell is a CIS-, CIGS-, CIGSS-, CdTe- or an Si-based (particularly Si/SiGe) thin-film solar cell.
