This current, comprehensive study of the literature provides a full review of recent developments in a variety of various kinds of solar stills. This review looks at studies on double-slope, hybrid solar stills, single-slope, with a condenser unit, and other particular types of solar stills. To make the work more relevant to readers, the authors provide a thorough summary of the latest research papers in the area of solar stills in addition to a general overview of the many varieties of solar stills. An overview of the various desalination methods is provided in this review paper. Although there have been notable advancements in desalination techniques, the systems' operational costs have remained high throughout time. With the use of cutting-edge technologies, efforts have been made to reduce the price of producing desalinated water. The cost of producing desalinated water is significantly reduced when solar stills are used for desalination. In this review paper that follows, innovative designs and methods for solar still desalination are being used to increase daily productivity while lowering production costs. Numerous changes were tried to extend the residence time and surface area of water that could evaporate, but these changes did not cause the feed water to remain in the still's basin for an extended period.
