Preparation of perovskite solar cells with regular n-i-p architecture and their optimization
Poláková, Simona ; Zmeškal, Oldřich (oponent) ; Pospíšil, Jan (vedoucí práce)
The diploma thesis deals with the study of perovskite solar cells with a regular n-i-p architecture. The theoretical part of this work is mainly focused on the stability of perovskite solar cells, i.e. thermal stability and the influence of UV radiation on final perovskite solar cell stability. Furthermore, the deposition methods, the architecture of solar cells and the materials used for the preparation of electron and hole transport layers were described in more detail. The experimental part deals with the optimization of the preparation of perovskite solar cells (especially in terms of resulting photovoltaic conversion efficiency), with a description of the structure preparation process of the final photovoltaic cell and the interpretation of the measured results.

Electrical noise in thin films of metal-free phthaloxyanine
Nešpůrek, Stanislav ; Šikula, J.
Results of the measurement of current-voltage (I ~ U) characteristics and current noises in this films of metal free phthalocyanine are reported. I ~ U curves are typical of space-charge-limited currents. The noise in low-frequency region is of the 1/f type. A generation-recombination noise prevails in the higher frequency region.
