Study on the Performance of Optimized Color-Sensitive Solar Cells

In this work, titanium dioxide nanoparticles, titanium dioxide nanofibers and zinc oxide nanoparticles were synthesized by sol-gel method and the structure and performance of these nanomaterials on color-sensitive solar cells along with carbon nanotubes as cathodes have been discussed using XRD, SEM, and cu-rrent–voltage curve. The results of XRD analysis of titanium dioxide and zinc oxide nanoparticles showed that these particles have good crystalline structure without any impurity peaks in the graphs. According to the result, titanium dioxide nanofiber shows the best electrical efficiency, which is shown by the slope of the current–voltage curve for this sample among the titanium dioxide nanoparticles and zinc oxide nanoparticles.
