Development and Analysis of Inorganic Perovskite material for Solar Cells

Abstract

In this work, for the first time, a blend of a prepared nano barium titanate (BaTiO₃) using the hydrothermal method and Cs₃Bi₂I₉ was used as a perovskite material for photo anode layer fabrication to be used in photovoltaic pv solar cell. This prepared layer was characterized through XRD, SEM and UV-Vis spectroscopy and the findings state that the band gap of the prepared layer was reduced further compared to the original material of barium titanate (insulating material) suggesting that the prepared material is promising in the PV cell. This fact was further confirmed through performance testing, which showed that the short circuit current (Isc) measured 5 mA and the photoconversion efficiency (PCE) was 2.4%. It was found the morphology of the prepared layer was also improved.
