“…[16] carried out green synthesis of nanoparticles by biological systems they reported peaks absorption around 350 nm due to large excitation binding energy at room temperature. ZnO nanoparticles was blended with a poly-3-hexyl-thiophene as active material for high performance solar cell by [17,18] blended ZnO.NPs with P3HT and an improvement was reported in interchains and intrachains ordering when compared to pure P3HT. Power conversion efficiency of solar cells also improved.…”

Efforts has been intensified in the field of research for nanomaterials to bridge the gap for energy supply in this century. A plant-based material that may provide solutions to the current energy crisis may be found in nanomaterials. Green synthesis of nanoparticles using plant extract is gaining importance as an alternative to conventional chemical and physical method of synthesis, because of its simplicity and environmental friendliness. In this research we synthesized Zinc oxide nanoparticle (ZnO.NPs) using plant extracts and deposited using spin-coating technique. The obtained samples were characterized by UltraViolet-Visible spectrophotometer, Fourier Transform Infra-Red spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Solar simulator for electrical properties. The maximum absorption peaks occurred at 235 nm, 250 nm, 270 nm, and 300 nm respectively but lower when compared with the bulk size that occurred at 350 nm and in the visible spectrum of the wavelength band. Band gap energy of zinc oxide nanoparticle at 500 rpm was 3.50 eV. ZnO.NPs FTIR spectrum was recorded in the range of 4000-500 cm −1 . The synthesis ZnO NPs FTIR result shows Zn-O functional group was found at low wavenumber. SEM images of the samples give information on the morphology which are spherical and granular nature. The XRD pattern of synthesized nanoparticles shows that the substances only belong to ZnO since there is no diffraction peaks of other impurities and the average grain size of the particles was estimated to be 14.7 nm. ZnO.NPs thin film device under illumination has efficiency of 0.7%. Based on electrical properties of the fabricated thin film device, the parameter shows it could be suitable for photoanode of Dye sensitized solar cell.
