Improving the efficiency of dye-sensitized solar cells based on rare-earth metal modified bismuth ferrites
Abstract
<jats:title>Abstract</jats:title><jats:p>This study reports light energy harvesting characteristics of bismuth ferrite (BiFeO<jats:sub>3</jats:sub>) and BiFO<jats:sub>3</jats:sub> doped with rare-earth metals such as neodymium (Nd), praseodymium (Pr), and gadolinium (Gd) dye solutions that were prepared by using the co-precipitation method. The structural, morphological, and optical properties of synthesized materials were studied, confirming that 5–50 nm sized synthesized particles have a well-developed and non-uniform grain size due to their amorphous nature. Moreover, the peaks of photoelectron emission for bare and doped BiFeO<jats:sub>3</jats:sub> were observed in the visible region at around 490 nm, while the emission intensity of bare BiFeO<jats:sub>3</jats:sub> was noticed to be lower than that of doped materials. Photoanodes were prepared with the paste of the synthesized sample and then assembled to make a solar cell. The natural and synthetic dye solutions of <jats:italic>Mentha, Actinidia deliciosa</jats:italic>, and green malachite, respectively, were prepared in which the photoanodes were immersed to analyze the photoconversion efficiency of the assembled dye-synthesized solar cells. The power conversion efficiency of fabricated DSSCs, which was confirmed from the I–V curve, is in the range from 0.84 to 2.15%. This study confirms that mint (<jats:italic>Mentha</jats:italic>) dye and Nd-doped BiFeO<jats:sub>3</jats:sub> materials were found to be the most efficient sensitizer and photoanode materials among all the sensitizers and photoanodes tested.</jats:p>
