Crystalline quality assessment, photocurrent response and optical properties of reduced graphene oxide uniformly decorated zinc oxide nanoparticles based on the graphene oxide concentration

Abstract

Zinc oxide nanoparticles–reduced graphene oxide composites with a high degree of crystallinity and high dispersity were successfully synthesized <italic>via</italic> a facile sol–gel one-pot method in a starch environment as a natural surfactant for the fabrication of solar cell devices.
