ZnO/natural dyes solar cell (DSSC) had been successfully synthesised. The preparation of ZnO thin films was carried out on an indium thin oxide (ITO) glass substrate using the sol-gel spin coating method. The natural dyes were extracted from tamarillo, red dragon fruit, red spinach, boat lily flower and purple hibiscus flower, each cut into small pieces and put into a beaker glass. The sample was then further crushed with a mortar and then milled until it became soft. The extracted dyes were heated for 5 h and diluted with distilled water to obtain dye solutions. The DSSC structure was formed by glueing together the ZnO/dye and a platinum plat by using Surlyn. The ZnO/dye and platinum were successively used as a working electrode and counter electrode. The Surlyn functioned as glue and conductor. The DSSC structure then put on a hot plate with a temperature of 70°C-80°C to enable Surlyn pasted perfectly. Further, electrolyte liquid was injected into the ZnO/dye-platinum structure. The ZnO thin films were characterised by X-ray powder diffraction (XRD), scanning electron microscope (SEM) and UV-Vis spectrometer. The ZnO/natural dyes thin films were formed by dipping the ZnO thin film into natural dyes solution with the ZnO thin films facing up for 24 h to let the dyes adsorbed by the film. DSSC efficiencies were measured by a simple circuit consisting of DSSC, both analogue and digital multimeters. The results showed that the ZnO crystal structure was of wurtzite hexagonal shape with a crystallite size of 27.3 nm, high-density granules with narrow inter granules boundary, and the band-gap was 3.25 eV. The maximum and minimum values of the sensitisers were from red spinach and red dragon fruit which were 3.30 a.u and 2.50 a.u. The DSSC can convert solar energy to electrical energy with power and efficiency of consecutively of 0.101 W cm -2 and 0.278%.

This article reports the effects of natural plant proteins on the morphology of zinc oxide nanoparticles (ZnONPs) prepared via a precipitation method. Green synthesised ZnONPs have a wide range of uses such as biomedical applications, water purification, optical devices and gas sensors. The non-toxic and economical technique described in this article is favourable for large-scale production too. ZnONPs were produced from a zinc acetate precursor with dye extract of Ixora Coccinea (IC) leaves as a capping agent. The as-prepared ZnONPs were characterised by X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV-visible (UV-vis), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques. The XRD analysis showed an average crystallite size of 23 nm. The SEM analysis revealed a reduction in aggregation of ZnO crystallites due to addition of dye extracts of IC. EDX and UV-vis results confirmed the formation of pure ZnONPs. Finally, the gas sensing properties of ZnO films, prepared by doctor blade method, were used to detect ethanol vapour. The results showed gas response ratios of 28.7 and 5.4 at 800 ppm and 40 ppm exposure, respectively. Furthermore, the response time and recovery time were found to be 24 sec and 47 sec, respectively at 200 ppm exposure of ethanol vapour.
