The efficiency of solar photovoltaic (PV) power generation is significantly impacted by factors such as ambient temperature, surrounding wind speed, and the temperature of the solar PV panels. The power generation efficiency of these panels diminishes by approximately 0.5% for each incremental rise in their temperature. To mitigate this effect, two primary methods for cooling solar photovoltaic panels are considered: active and passive cooling techniques. This review paper delves into an extensive body of literature on solar passive cooling systems, highlighting the vital role of passive cooling technology in enhancing the efficiency of solar PV power generation. We investigate the structure and cooling effect of diverse passive cooling systems, with a specific focus on the application of solar chimneys and ventilators in cooling systems for solar PV panels. Our study reveals that solar chimneys, using buoyancy, can decrease the temperature of solar PV panels by as much as 15 degrees, thereby augmenting power generation efficiency. Furthermore, the deployment of ventilator technology can boost the efficiency of solar PV power generation to an impressive 46.54%. In conclusion, this paper proposes the synergistic use of solar chimneys and ventilators to improve solar PV panel efficiency, extend their lifespan, and reduce the environmental impact resulting from inefficient solar PV panels. This comprehensive approach should inform future practices.

“…In general, solar cell performance is influenced by external factors, such as ambient temperature and solar radiation [38]. The power generation of solar cells decreases by approximately 0.33% [39] for every degree Celsius in the environment above the standard temperature of 25 °C. Therefore, the actual power generation efficiency of the solar power station is lower than the simulation results.…”

People are increasingly using clean energy sources, contributing to environmental protection according to the general trend of the world. In the form of renewable energy, solar energy has contributed to solving current pressing problems, such as environmental pollution and air pollution, improving people’s quality of life. The design of solar power projects in Vietnam is mainly based on meteorological data sources from Meteonorm and NASA. However, the accuracy assessment of two data sources compared to the actual solar power data in Vietnam is not available, so there is no basis to determine better meteorological data source quality to serve the design of rooftop solar power projects. The content of this paper analyzes the simulation results of a typical rooftop solar power station at the Electric Power University, Hanoi city based on meteorological data sources from Meteonorm and NASA. After that, the simulation results will be compared with the actual operating data of a rooftop solar power station near the Electric Power University and other real PV systems in the world. The study results showed that the amount of electricity production using the Meteonorm meteorological data was closer to the actual data than the NASA data source. Therefore, solar power projects in Vietnam should use Meteonorm data source for the design process to determine the best economic and technical efficiency for investors.

“…The demand for energy worldwide is projected to increase due to human activities. In this context of high energy demand, photovoltaic materials, which transform the sunlight into electricity, are nowadays one of the most practical solutions to generate clean and environmentally friendly energy [1,2] with photovoltaic cells (PV). The efficiency of these cells, defined as the percentage of solar energy converted into usable electricity, is a crucial factor in making PV technologies cost-competitive with conventional energy sources.…”

Compounds based on chalcogen elements are widely studied currently due to their many interesting applications for electronic devices. The sodium-based dichalcogenide (NaNbS$_2$) is a fascinating material with storage and conversion energy applications. In this paper, we conduct a first-principles investigation ofthe structural and thermodynamic stability and electronic propertiesof this material. We analyzea total of four structures to find the ground state using a fourth-order Birch-Murnaghan equation of state: the $\alpha$ and $\eta$ related to the A-phase and the $\zeta_{1}$ and $\zeta_{2}$ related to the B-phase.We carefully address the exchange-correlation effects using the semi-local GGA-PBEsol targeted for solids. To analyzethe electronic structure with higher accuracy, we implement the quasi-particleG${\textup{o}}$W${\textup{o}}$ approximation. \textcolor{red}{Our results for the fourth-order Birch-Murnaghan equation show that the most thermodynamically stable phase at zero temperature is $\alpha$.} To provide experimentalists insights about the possible routes to grow these materials, we calculated the convex hull of the $\alpha$-model and $\zeta_{1}$-model, finding that both are energetically stable.Finally,the calculated band gap with quasiparticle corrections for the $\alpha$-model is 1.03 eV, which suggests possible applications of this material as a bottom cell in modern solar cells.
