Design and production of dye-synthesized solar cells with FTO/TiO2/ferroelectric dye/electrolyte/Pt/FTO architecture

Abstract

A new approach for the application of dye-synthesized solar cells is realized by using perovskite and single oxide micro/nanopowders. With respect to the literature, the desired energy efficiency of dye-synthesized solar cells is a priori established as perovskite and single oxide micro/nanopowders in a composite structure. In the present work, in order to produce dye-synthesized solar cells with FTO/TiO₂/ferroelectric/dye/electrolyte/Pt/FTO architecture, their precursor solutions were prepared by using nitrate-based salts, solvents, and chelating agents. The obtained gel films were dried at 200 °C for 2 h and then annealed at temperatures of 500 °C and 850 °C for 2 h in the air. TiO₂ and LaFeO₃ powders were characterized through DTA-TGA, FTIR, XRD, SEM, and UV-Vis spectrometer machines. In line with the results obtained, dye-sensitized solar cell production, which can also be called ferroelectric photovoltaic cells with a combination of TiO₂, was produced. It was found that the production of continuously applicable and sustainable dye-sensitive solar cells using LaFeO₃ with together TiO₂ powders can be useful as innovative and futuristic approaches.
