Abstract In the present study, solar still performance has been investigated under different operating conditions such as coating the basin liner by TiO2 nanoparticles mixed with Cr2O3 and different combinations of hybrid bond adsorption. The basin liner was a copper sheet which was used to adsorb energy in winter & summer (W&S). The mixture of TiO2 nanoparticles and Cr2O3 was characterized by SEM, FTIR and XRD tests. Results revealed that the average daily productivity of the solar still was 5.39 and 7.89 L during the winter and summer, respectively. The average daily efficiency of the system was 57.16% and 36.69% through the summer and winter, respectively. Based on the analysis, the best performance of the solar still can be achieved during winter and summer conditions of K L University of Andhra Pradesh, India.
