Abstract: In this paper, we will discuss the classifications of the solar still and the influences on its operation. And the effect of some additions on the productivity of the solar still,.we will make several comparisons on the traditional Solar Still device with the addition of some accessories that affect the performance of the device (fins and magnets), provided that the work of the device remains passive by studying some experimental and theoretical research published in this field to know the effect of these additions, types, preparation and Their sizes and the way they are arranged inside the device basin so that we can have a clear view of a good starting point in the upcoming work to develop the work of the device and reach better productivity.
Keywords: Solar Desalination, Phase Change Material , fin, Graphite, passive solar still
I. INTRODUCTION
One of the most important renewable energy sources is solar energy, sustainable and environmentally friendly energies in the first place, which can be exploited in many fields. Where the sun provides us with heat and light. Light is used to generate electrical energy, as for the heat generated by solar radiation, it is used for many different purposes.There is a finite amount of fresh water on planet. Over two-thirds of the surface of the world is covered by water, but more than 97% of that water is either salty or contaminated. Fresh water makes up the remaining almost 2.6%. The amount of fresh water that humans and other organisms can access is less than 1%. Even this tiny fraction is thought to be sufficient to sustain life on Earth, but as the population grows, so does the demand for fresh water. Water that has been contaminated cannot be utilized for drinking purposes since it contains dangerous microorganisms and dissolved substances. The world faces a shortage of fresh water and drinking water in both wealthy and developing nations. The techniques utilized to produce fresh water[1]. Kuan, M., et al (2019) [2] numerically analyzed the performance of a heat pump–assisted solar still with the concept of latent heat released during the condensation of water vapor regenerated using compression heat pump for preheating the inlet saline water before entering into the solar still basin. They improved the productivity by about 62% when compared to CSS during summer climate conditions . Hansen et al. (2015) [3] researched an inclined solar still with different new wick elements and wire mesh. Various wick elements related to the
