Study of multilayer perovskite structures properties
 Gabzdyl, Adam ; Kratochvíl, Matouš (referee) ; Pospíšil, Jan (advisor)
The bachelor thesis focuses on the optical, electrical and dielectric properties of perovskites and their multilayer structures for use in optoelectronic applications. Samples of lead MAPbI3 and lead-free Cs3Bi2I9 perovskite in a photovoltaic cell of FTO/SnO2/perovskite/spiro-OMeTAD/Au structure were prepared and studied. The optoelectrical properties were determined by direct current measurement of current-voltage characteristics and the dielectric properties were determined by impedance spectroscopy. It was determined that with this photovoltaic cell structure, lead perovskites are a more suitable material for optoelectronic applications than lead-free perovskites because they exhibit many times higher solar energy conversion efficiency and possess more favorable electron processes.
