Solar still owns low distillate productivity. Many researchers enhanced the performance of solar still by variable the design of its components. The combination of internal/external reflectors, absorber materials (fins, sponge, pebbles), and external condensers had a substantial impact on the absorption, evaporation, and condensation processes of the classic basin type solar still. This paper is showing how existing methods for increasing solar still absorption, evaporation, and condensation may be used to improve solar still absorption, evaporation, and condensation. From this review, it is found that for solar still, that adjusting the internal/external reflectors might increase daily distillate yield by 70% to 100%. Added Absorbent materials improve the thermal performance of a still by increasing production by over 20%. In addition, the external condensers enhanced still freshwater yield by 62% more than the regular still.

Recently, TiO2 nanotube arrays (TNTAs) have attracted researcher’s attention in the fields of energy production and environmental remediation applications; this is mainly due to their unique optoelectronic characteristics, corrosion resistance, chemical and mechanical stability. In this study, the ability of employing of TiO2 nanotube arrays-based catalysts in the field of photocatalytic CO2 reduction has been investigated. Possible modification strategies have been presented for improving the TNTAs performance by using different types of nanomaterials including graphitic carbon nitrides (g-C3N4), metal-organic frame work (MOF), reduced graphene oxide (RGO) and gold nanoparticles (Au NPs). The TNTAs composites were characterized using XRD and FESEM analyses and the results revealed the successful synthesis of these composites. The TNTAs and their composites exhibited good results for the photo-conversion of CO2 into CH4 gas product. This study gives new ideas for making and developing low-cost Ti metal-based nanomaterials which can be used in the future for recycling the CO2 gas emissions into useful solar fuels.

The study aims to estimate the amount and cost of hydrogen and oxygen that can be produced in the Al-Jufra region (Libya) using photovoltaic panels (PV). The electricity generated by PV is used to power the proton exchange membrane (PEM) electrolyzer. Through the study, the thermal efficiency of the system is calculated, as well as the factors affecting it. The amount of solar radiation that the region receives during the year is also determined, amounting to 81.72 kW/year m2, with a duration of 3421 daylight hours. With this radiation value, it is possible to produce 1272 and 636 mol/year m2 of hydrogen and oxygen, respectively, at an estimated cost of $1.42 per mole. Thermodynamic analysis of PV cells and electrolyzer shows that the electrical efficiency and exergy efficiency of PV cells are 4.8% and 5%, respectively, and vary according to the radiation intensity. The exergy and energy efficiency of the analyzer remained constant at 48% and 39%, respectively, according to the aforementioned arrangement. The decrease in the efficiency of PV energy efficiency affects the overall efficiency of the system and does not exceed 3% in ideal conditions. In addition, the expected cost in 2030 is estimated and found to be 5.77% lower than its current price. Comparing the amount and price of production in the Al-Jufra area with other areas in Libya, it becomes clear that the city of Al-Kufra has a 20% higher annual production amount.

This study explores how plasmonic nanoparticles affect absorption, transmission, and reflection—three important performance metrics in organic-inorganic halide perovskite solar cells (PSCs). Through an investigation of different types of nanoparticles and their concentration in the composite layer, the study provides important information for improving PSC design in order to increase overall efficiency. The results highlight the importance of the type and volume fraction of nanoparticles in the composite layer, which influence the spectral characteristics of the solar cell, such as absorption, reflection, and transmission. These findings could encourage PSCs to be widely used as a practical and affordable renewable energy source, which would advance the development of affordable and efficient solar energy technologies.
