Summary / Abstract: Solar energy is a clean and renewable source. Various technologies of solar cells have been developed, among which the perovskite photovoltaic technology is developing most rapidly recently. By using organometallic halide perovskite as an optical absorption layer, the power conversion efficiency of solar cells for hybrid organic-perovskites increased by more than 24 % in 2019 due to the high mobility of charge carriers and its good absorption over a wide spectral band. However, these materials show problems of stability, reliability and toxicity. Of course, research in this area is trying to solv these challenges, but success is not guaranteed. Alternatively, inorganic oxides, could present significant benefits. The ideal band gap for an active photovoltaic layer for the solar spectrum is approximately 1.3 eV [2]. Which makes ferroelectric semiconductor oxide perovskites feasible for photovoltaic solar cell applications with wide light absorption band and efficient energy conversion. In this project we propose to study a type of emerging and innovative potential photovoltaic technology based on Pb(Zn1/3Nb2/3)O3-PbTiO3 (PZN_PT) oxide ferroelectric materials in the form of nanoparticles deposited on nanostructured p-type silicon substrate.
