Abstract

<jats:p>One of the most crucial variables to consider while analysing the current conduction process in the metal organic Schottky contact is the Richardson constant. However, there aren't many publications on the determination of the useful Richardson constant for Fruit dyes. For two differentFruit dyes, Carmoisine, and Tartrazine, we have determined the values of the effective Richardson constant in this work. By using the spin coating method, a thin organic layer of these natural colours was sandwiched between a copper plate and a piece of glass that had been coated in indiumtin oxide. The current-voltage-temperature response of the cells was examined at a temperature range of 303K to 333K. The estimated effective Richardson constants for these dyes are 95.09 x 10<jats:sup>-3</jats:sup> A/cm<jats:sup>2</jats:sup>K<jats:sup>2</jats:sup> and 44.35 x 10<jats:sup>-3</jats:sup> A/cm<jats:sup>2</jats:sup>K<jats:sup>2</jats:sup>for CS and TZ dye respectively, which are different from the typical value of 120 A/cm<jats:sup>2</jats:sup>K<jats:sup>2</jats:sup>. We can analyse several electrical properties for these natural dyes with the aid of these values.</jats:p>
