Abstract: The utilization of solar desalination processes using solar stills to maintain the purity of water. The purpose of this process is to remove impurities and salt from water to make it suitable for consumption. The study involves analyzing various factors that influence the conditions of the solar desalination process at different stages. The article reviews the application of highly efficient materials and experimental endeavors in the realm of solar stills. One notable technique involves using Paraffin wax in combination with different Phase Change Materials (PCMs). This combination leads to increased productivity and thermal conductivity, ultimately enhancing the output of the solar still. In a modified solar still, the incorporation of wicks resulted in amplified distillate output and an overall improvement in productivity. Another enhancement strategy discussed is the utilization of nano-particles. The incorporation of these nano-particles led to improved daily efficiency and thermal conductivity. This, in turn, raised the thermal efficiency of the solar still and augmented the yield of fresh water. The article also underscores the efficacy of collective approaches involving Phase Change Materials, reflectors, and nano-coating paint mixed with nano-particles. These combined materials resulted in a notable increase in thermal efficiency and fresh-water yield. Among the various Phase Change Materials explored, the study concludes that paraffin wax exhibits the highest output and productivity compared to other options. In essence, the article highlights the advancements and innovations in solar desalination using solar stills.
