Summary: This study investigates the effect of using hybrid nanofluids for cooling on the performance of a two-dimensional photovoltaic thermal system, and aims to enhance the system's performance by varying parameters. The hybrid nanofluids used are made of water as the base fluid and a mixture of Copper and Aluminia oxide. The study uses finite element software to simulate the problem and conducts a parametric study by varying the inlet temperature, Reynolds number, volume fraction of Copper, and height downstream of the backward step channel. The study shows that increasing the amount of Cu in the base fluid, the upstream channel's height, and the corresponding Reynolds number improves the system's performance.

Summary: A hybrid PV/T collector/evaporator was designed and a hybrid system named PV-SAHP/GHP was proposed. Outdoor experiments were conducted to compare the operating characteristics of different modes. The results showed that the GHP-PV/T mode had satisfactory energy-saving effect while the PV-SAHP mode met the temperature demand but had unsatisfactory energy conservation effect. It is recommended to operate the GHP-PV/T mode during intense radiation and the PV-SAHP mode otherwise to balance the thermal performance and energy-saving benefits.

Summary: This paper analyzes the performance of photovoltaic thermal (PVT) panels in tropical climate regions. The combination of a heat exchanger with conventional photovoltaic (PV) panels in PVT systems improves the efficiency of PV panels and provides heat. The study deeply investigates the factors influencing PVT system performance and selects the most suitable parameters based on technical and economic considerations. The use of digital logic and merit index methods helps to select the heat exchanger material. The performance analysis of other aspects and variables is conducted through numerical simulation and validated with experimental results. The comparison with a conventional PV system using real weather data shows a significant improvement in efficiency for PVT systems.

Summary: Solar desalination is a sustainable solution for global water scarcity, especially in remote areas of developing countries. The integration of solar photovoltaic-thermal (PVT) with desalination can improve the efficiency, productivity, and independence of solar desalination processes. The combination of electrical and thermal energy outputs from PVT panels can catalyze the improvement of solar energy efficiency, specific energy consumption, water production, and operational independence for off-grid applications. Our analysis suggests that PVT-desalination can be a more cost-effective and sustainable solution compared to current solar PV-desalination and ST-desalination.
