Effect of Different Concentrations of Titanium Dioxide Nanoparticles on the Potential Barrier of Organic Device

Abstract Present work has studied potential barrier of Phenosafranin dye based organic device and observed influence different concentrations titanium dioxide nanoparticles on this parameter. We have made devices by taking weight ratios the – blend which are 1:1, 1:2, 1:3 1:4. These been formed varying keeping same content. One is also without any nanoparticle to compare device. sandwiching in between Indium Tin Oxide coated glass Aluminium mylar sheet. The measured from device’s I-V plot Norde function. two methods remain good agreement showing that mostly decreased when concentration highest nanoparticles. ratio –nanoparticle 1:4 shows lowest it nanoparticle. reduced presence higher can be ascribed improved filling traps. Lowered at metal contact will improve charge flow resulting better performance
