Abstract: A thin-film solar module with a substrate and a layer structure applied thereon that comprises a rear electrode layer, a front electrode layer, and an absorber layer arranged between the back electrode layer and the front electrode layer. Serially connected solar cells are formed in the layer structure by patterning zones, wherein each patterning zone comprises a first patterning line for subdividing at least the rear electrode layer, a second patterning line for subdividing at least the absorber layer, and at least one third patterning line for subdividing at least the front electrode layer. At least one patterning zone has one or more optically transparent zones in a zone region reduced by the first patterning line, which are in each case rear-electrode-layer-free, wherein the one or more optically transparent zones are implemented such that the rear electrode layer is continuous in the zone region.

Abstract: A telemetry system for obtaining loggings by an independently guiding logging probe provided with a sensor includes the logging probe ejected in a drill string, so that the sensor projecting through a drill bit of the drill string has an access to the bottom and walls of the drill bore, a pick-up probe injectable into the drill string to form a wireless connection with the logging probe and connected to a portable computer which initializes the logging probe, loggings stored in the logging probe are readable from the portable computer upon recovering the logging probe from the bore string.
