“…In this process, the conversion of Cu to CuO is dependent on the change in absolute temperature (1 °C/min). Moreover, the presence of oxygen plays a key role in changing the sphere-like morphological arrangement in CuO [9,11].

“…Nano energy (NPs + solar energy) have been used to evaporate the wastewater for desalination [37,39,65,68,69,73]. These nano-enabled materials shift attention back towards the traditional solar-evaporation systems, simply called "solar stills" (SSs) [5-9, 11-13, 40, 42, 46, 53, 55] capable of producing more than 5 l/m 2 day [9,11]. The effect of nano-coated condensation surface was developed to augment the evaporation in the solar still [71].…”

Solar energy is one of the most powerful sources for many sustainable applications. Recently, efficient water distillation has attracted significant attention. The fresh water productivity depends on how efficiently the system harvests the incoming solar energy and converts it into useful heat. In the present work, nano-coated absorber plates (NCAPs) were examined in the single slope solar still (SSSS) for clean water production. The NCAPs were CuO, MoO 3 and ZnO, respectively. The CuO-NCAP was fabricated with the thermal evaporation method while the radio-frequency Magnetron Sputtering technique was used to fabricate the MoO 3 and ZnO NCAPs. The attained particle size of the CuO, MoO 3 and ZnO are 30-34 nm, 25-30 nm and 30-35 nm, respectively. The sphere (CuO), plate (MoO 3), and wedge (ZnO) like morphologies are identified with field emission-scanning electron microscope. All the NCAPs and reference solar still were tested under the same environmental conditions. The climatic parameters (solar influx, ambient temperature and wind) and SSSS's temperatures including water temperature (T w), internal air temperature (T int-air), inner cover (T ic), outer cover (T oc), and absorber plate temperature (T NCAP) were measured at 30 min intervals with the help of Type-J thermocouples. Herein, we present an evaporative heat transfer (h ew), efficiency, and cost analysis of the SSSS with CuO, MoO 3 and ZnO-NCAPs. Three different feed waters fetched from the surface well water, hill side well water and hill side pond water were used in this work for evaporation. The result reveals that the evaporation of conventional single slope solar still, CuO, MoO 3 and ZnO NCAPs were 2.1 l/m 2 day, 2.9 l/m 2 day, 2.7 l/m 2 day and 2.6 l/m 2 day, respectively.

This study is intended to comparative and analyze the operational performances of the conventional hemispherical solar still (CHSS), hemispherical solar still with glass cover cooling (HSS-C), and hemispherical solar still with CuO-water based nanofluid (HSS-N). To Obtain the best modifications that achieve the highest productivity with the lower inexpensive. The conventional hemispherical still (CHSS) was utilized as the reference case to investigate the best modification. In the first modification, CuO nanoparticles with three different concentrations (0.1, 0.2, and 0.3%) were added to the basin water, to increase the intensity of absorbed solar energy, improve the thermal properties of basin fluid, and then increase the rate of vapor generation inside the distillation basin. In the second modification, water film glass cooling technology with three different flow rates (1.5, 2, and 2.5 L/h) was utilized to increase the water vapor condensation rate. The experiments test of the three distillers (CHSS, HSS-N, and HSS-C) was conducted at the same weather conditions at 1 cm basin fluid depth. The average daily accumulative yield of CHSS is 3.85 L/m2/day, while the daily accumulative yield of HSS-N increases to 5.75, 6.40, and 6.80 L/m2/day with improvement 49.3, 66.2, and 76.6% at volume fraction 0.1, 0.2, and 0.3%, respectively. Also, the daily accumulative yield of HSS-C increases to 4.9, 5.35, and 5.7 L/m2/day with improvements of 27.3, 39, and 48% at water film flow rates of 1.5, 2, and 2.5 L/h, respectively. The cost of distilled water produced from CHSS is 0.0106 $/L, while the utilization of HSS-C (2.5 L/h) and HSS-N (0.3%) reduces the cost of distilled water to 0.0072 and 0.0066 $/L, respectively. Based on accumulative yield and economic analyzes, it is recommended that utilized the modified HSS-N (0.3% volume fraction) to achieving the highest accumulative yield and the lowest price of the produced distilled water.
