Abstract

People who live in isolated coastal locations currently struggle to find clean drinking water in many areas. There are a number of ways to obtain pure drinking water; however, the solar still (SS) remains the most effective one due to its affordability, environmental friendliness, and straightforward design. The conventional SS must be modified using alternative techniques because it has a lower production yield despite being cost-effective. In this context, the goal of this study is to review the published articles pertaining to the incorporation of various performance enhancing approaches into direct SSs for the generation of fresh drinking water, including nanoparticles, nano-PCM, hybrid nanoparticles, fins, and sponges. Reviewing the publications findings indicates that the production of fresh water is greatly increased by using hybrid nanoparticles and copper balls with PCM (4460 ml/m2-day). Additionally, the sponge and aluminium absorber plates contribute to a 10%, and 30% improvement in productivity, respectively. The study also discusses potential areas for future research as well as challenges and opportunities for applying the SSs in developing nations. It is important to look at the studies of SSs in the areas of sustainability, exergy, exergo-economics, and energy as well as the characterization of hybrid nanoparticles. Future research is also necessary into the application of various PCMs with nanoparticles, hybrid nanoparticles, and carbon nanotubes.
