Planary talk at the EU-PVSEC 2015. Perovskite/crystalline silicon tandem solar cells are one of the most promising approaches to reach conversion efficiencies beyond 30 % at reasonable costs. Our research includes fundamental studies on the perovskite material properties such as sub-band gap absorption and complex refractive index, as well as the development of a broadband transparent rear electrode. The electrode development enabled the fabrication of semitransparent perovskite cells with efficiencies up to 14.7 %, which then translates to four-terminal tandem measurements with total stabilized efficiency of up to 22.8 %. Furthermore, we present first results on monolithic perovskite/silicon tandems with total current of 32.25 mA/cm2 on a flat wafer and finally provide optimization guidelines with optical simulations.

D.10 Educational activities
COBISS.SI-ID: 11162196All-rotating unmanned aerial vehicles represent a young and very interesting subset of aircraft with rotating wings, mainly due to the exceptional aerodynamic properties. In addition to many advantages they bring demanding challenges for sensing position and orientation of the aerial vehicle. The main challenges in the realization of electronic systems for the management of this type of aircraft covered in the doctoral dissertation are: the problem of suitable sensor system, the problem of assessing the orientation of all-rotating aircraft based on the sensor data, the problem of poor knowledge of the dynamic characteristics of the aircraft, and the problem of real-time implementation of algorithms for the operation of the aircraft.
