Abstract

The worldwide energy crisis has motivated the search for new sources of clean and renewable energy, among which the use of the photovoltaic effect for the capture of solar energy has been highlighted. Among various types of materials that can be used for solar cell applications ferroelectric and multiferroic perovskite structures have received great attention in recent years. In this project, thin films of ferroelectric and multiferroic perovskite will be deposited by "RF Sputtering" aiming the optimization of their photovoltaic properties. Among the systems we propose to investigate in this project are complex perovskites of Pb (Fe, B) O3 (B = Nb, W, Ta, Ti) and solid solutions of Pb (Fe, B) O3 - Pb (Zr, Ti) O3, in addition to lead-free perovskites based on K (Na, Nb) O3. The various parameters that influence the photovoltaic effect in these systems, such as band gap, spontaneous/remnant polarization, electrical conductivity, electrode/interface properties, among others, will be investigated by optical, electrical, dielectric and ferroelectric techniques, in macroscopic and nanoscopic scale , aiming at understanding and optimizing the photovoltaic response. In the compositions, in which the absorption band lies the central region of the solar spectrum, the photovoltaic efficiency will be determined in prototypes of solar cells. (AU)
