While ferroelectric materials are widely exploited in microelectronics as dielectrics, studies also consider their use in areas such as information storage, and in particular photovoltaic (PV) cells. The objective of the thesis is to develop photovoltaic cells using Bi2FeCrO6 (BFCO), a ferroelectric material with a band gap that allows efficient absorption of UV and visible light. The challenge is to improve the optoelectronic properties of this material, which are strongly dependent on the Fe-Cr cationic order. This order can be controlled by modulating the deposition conditions and in particular the frequency of the laser shots during the growth of thin films by pulsed laser ablation. A study on the growth conditions of BFCO on SrTiO3 and...
