Abstract: To desalinate saline water and produce pure water, it is possible to use solar still technology (which is based on solar energy). This energy is abundant, free, renewable, and does not harm the environment. Because solar stills depend on solar radiation, their working time is only during daylight hours. Phase transition materials are used to maintain the freshwater production process’s continuity while also increasing the solar still’s productivity and efficiency. These materials are characterized by their ability to store and release large amounts of heat (latent heat) during the phase change. The daily production of solar stills can increase (50-125%) work (PVP K30: polyvinyl pyrrolidine, and PAA: polyacrylic acid) contribute to increasing the working hours of the distiller between (3-4) hours after sunset. Thus, the daily production quantity amount can increase by (50-75) %.
