“…Meanwhile, integration with humidification-dehumidification systems [ 71 , 72 ], thermoelectric modules (for heating and cooling) [ 73 , 74 ], and external/internal condensers [ 75 , 76 ] are another modifications for enhancing the performance of system. Furthermore, utilizing various solar collectors such as flat plate collector (FPC) [ [77] , [78] , [79] , [80] ], solar dish concentrator (SDC) [ 81 , 82 ], parabolic trough concentrator(PTC) [ 83 , 84 ], Fresnel lens (FL) [ 85 , 86 ], evacuated tube collector (ETC) [ [87] , [88] , [89] , [90] ], mini/shallow solar pond [ 91 , 92 ], and photovoltaic (PV) and photovoltaic/thermal (PV/T) [ [93] , [94] , [95] , [96] ] are other methods to improve the performance of solar stills.

“…It boosted convective heat transfer and productivity by 48% and 38%, respectively, according to Mehdizadeh Youshanlouei et al 33 To improve CSS productivity, energy, and exergy efficiency by 21.7%, 31.3%, and 22.6%, Dubey and Mishra 34 employed ring magnets and galvanized iron sheet metal. Sadeghi and Nazari 35 improved water output and energy efficiency by 218% and 117% over CSS by an active system with magnetic nanofluid (0.08%). Dhivagar and Mohanraj 36 used graphite plate fins and magnets to increase exergy and energy efficiencies by 1.81% and 21.46% above CSS.…”

The use of different energy storage materials can have a high effect on the water productivity of solar desalination. This study evaluates the impact of magnetic powders on modified solar still (MPSS) performance and compares the results with conventional solar still (CSS). Black iron oxide magnetic powder was selected to increase solar radiation absorption. The black iron magnetic powder simultaneously acts as a thermal storage material and a porous absorber medium. The thermal energy stored in the magnetic powder improved the performance of the MPSS during peak solar irradiation hours, resulting in higher productivity. The results showed that the thermal performance of MPSS was higher than CSS. The MPSS exhibited a 39.8% higher evaporative and 14.5% higher convective heat transfer rate compared with CSS. Results showed that the cumulative water productivity of MPSS was 31.2% greater than CSS. Also, the energy and exergy efficiencies of MPSS were improved by 18.9% and 19.04%, respectively, compared with CSS. Moreover, the predicted payback period in MPSS and CSS were 3.2 and 4.3 months. Additionally, the CO 2 reduction of MPSS was improved by approximately 45.53% compared with that of CSS. The results also showed that the exergoeconomic parameter of MPSS and CSS with energy base was equal to 33.1 and 24.56 kWh/$, respectively.

“…In this system, the water temperatures at the outlet heater differed by about 20%, which means that the proposed system enhanced the temperature of the water for the central processing unit-type heat exchanger. Sadeghi G. and Nazari S. [27] presented the purification of water using a hybrid nanomaterial and the application of the magnetic property to increase the rate of heat transfer. This study included two types of a solar still, one of which was conventional.…”

In this paper, an experimental investigation study was conducted to show the effect of enhancing the evaporation and condensation processes inside a modified solar still by placing ultrasonic humidifiers inside a cotton mesh tent in the basin water and by installing a cooling chamber with thermoelectric elements on top of the solar still. Various parameters were recorded every hour, such as temperatures at different points within the solar still, the weather conditions (e.g., solar irradiance intensity, ambient air temperature, and wind speed), the yield of distilled water, and thermal efficiency on 29 July 2021 at the Ural Federal University (Russia). The production cost of distilled water from modified and traditional solar stills was also estimated. The experimental results showed that the productivity of the modified solar still increased by 124% compared with the traditional solar still, and the highest thermal efficiency was recorded at 2:00 p.m. (approximately 95.8% and 35.6% for modified and traditional solar stills, respectively). Finally, the productivity cost of distillate water (1 L) was approximately 0.040 and 0.042 $/L for the modified and traditional solar stills, respectively. The current work has contributed to increasing solar still productivity by applying simple and new technologies with the lowest possible capital and operational costs.
