Various modes of phase changing material (PCM) enrich the still outcome productivity of distilled water

Thermal energy from solar can be effectively stored through the use of phase changing material (PCM) that combines copper oxide with PCMs. In order to utilize solar energy effectively, it will require a storage medium that can store excess energy and then furnish it when it is needed. The present study describes the preparation of copper oxide nanoparticles via co-precipitation method, the fabrication of a passive-type single-basin double-slope solar still and its experimental testing in three different modes: (1) Solar still without PCM (2) Solar still with PCM (3) Solar still with NPCM. The main focus is on evaluating productivity yield rates without PCM, with PCM, and NPCM. An analysis of copper oxide for XRD, FTIR, UV, PL, and TEM images of CuO nanoparticles was conducted to establish the structure, crystallinity, and morphology of the nanoparticles. In order to boost the productivity of distilled water, the PCM is substituted with CuO nanoparticles. A series of measurements were made of the temperature of the water, the temperature of the basin, the temperature of the glass top, and the temperature of the PCM tube. Analyses of thermo-gravimetry have been performed on PCM and NPCM to study their exothermic and endothermic processes. A series of measurements were made of the temperature of the water, the temperature of the basin, the temperature of the glass top, and the temperature of the PCM tube.
