Monodispersed ZnO Nanoparticles and Their Use in Heterojunction Solar Cell

الملخص EN

Monodispersed ZnO nanoparticles have been synthesised in ethylene glycol medium using zinc acetate and sodium hydroxide at room temperature through ultrasonic treatment.

The monodispersed ZnO nanoparticles were characterized by XRD, TEM, SEM, and optical spectroscopy.

The results indicate that ZnO shows the hexagonal wurtzite structure having 8 nm average particle size with the band gap of 3.93 eV.

ZnO nanoparticles blended with P3HT show the improvement in the interchains and intrachains ordering as compared to pure P3HT.

The power conversion efficiency of P3HT/ZnO solar cell is found to be 0.88%, which is comparable with the result obtained by other researchers.
