Realization of a Si nanowire-based solar cell. Growth of gold-catalyzed Si nanowires patterned e.g. by nanosphere lithography. Experimental studies and thermodynamic calculations of the Al Induced Crystallization process.

Step-by-step synthesis and characterization of solar cells produced using company-developed nanomate- rials, studied for different process parameters within optimized ranges. Their characterization includes crystallinity studies of the sintered nanomaterial, measurement of IV-curves and record of degradation in time.

Synthesis of organized gold nanoparticles by nanosphere lithography combined with sputtering. Studies about the influence of different annealing temperatures and spinning conditions. Characterization of the patterns by SEM, AFM, GDEOS (see “Publications”). EBSD measurements of Si nanowires. Preparation of FIB-FEBID gold patterns.

Transmission measurements and losses evaluation with various sources (laser, Erbium - Doped Fiber Amplifier, broadband) of sets of waveguides. Comparison of the results with calculated band structures.

Angle-resolved photoluminescence measurements of porous Si dielectric multilayers synthesized by electrochemical HF-etch after simula- tions with a MatLab program. Comparison with spectra taken after oxidation or impregnation with water or water-solved porphyrin.
