Energy Storage Materials Performance and Assessment of Single Solar Distiller using a Natural Dye created by doping TiO2 with Dragon Fruit

Abstract

There is no longer a decent water shortage in rural or urban locations, and solar distillers' lower productivity is a result of their low cost and benefits. Therefore, design modifications were developed and tested in the summer (S) and winter (W) to maximize the output of the single solar distiller (SSD). This is accomplished by coating the distiller's absorber plate's backbone with dye made from Dragon fruit peel extract with TiO2 nanoparticles (DFPETN). The absorption spectra of the DFPTEN has a peak value of 535 nm and studied using UV-Vis. techniques. Finally, both conventional solar still (CSS) with & without coated DFPETN using SSD is evaluated in terms of their thermal, exergy, environmental, and economic possibilities. The outcomes showed that the SSD by DFPETN@30% yield was superior to that of the other DFPETN ratios. Moreover, the benefit of DFPETN@30% with coated the basin area to more yield of SSD has been reported as 4.026 kg/m2.daytime in summer (S), 3.958 kg/m2.daytime in winter (W) with a compared to 1.637 kg/m2daytime (S) and 1.629 kg/m2daytime (S) for the CSS, accordingly with improvement by 179% in SSD. The overall SSD efficacies with DFPETN@30% during the S and W have increased by around 38.87% and 34.69%, the exergy efficiency is 5.8% respectively, and CSS is 8.23% in the S and 7.14% in the W. The SSD with DFPETN@30% has an environmental parameter of 12 tones CO2 year and water costs is 0.24 and 0.10 $/L, respectively. We successfully demonstrated the utility of the SSD is utilizing dragon fruit as TiO2 in the creation of an inexpensive, environmental friendly solar distiller.
