“…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.
