The electrical efficiency of the photovoltaic (PV) panel is affected significantly with increased cell temperature. Among various approaches, use Phase Change Materials (PCMs) nanoparticles currently one most effective for reducing and managing temperature PV panels. In this study, paraffin wax as PCM different loading levels (0.5%, 1%, 2%) hybrid Al2O3 ZnO were successfully synthesized their effects on performance Photovoltaic-Thermal (PVT) system investigated experimentally. Additionally, a prediction model was developed to analyze interaction between operating factors (independent variable) response (dependent PVT/PCM PVT Hybrid nano-PCM (PVT/HNPCM) systems based surface methodology (RSM). Experimental results showed that compared only PCM, thermal conductivity HNPCM by 24.68%, 28.57%, 41.56% inclusion 0.5%, 2% nanomaterial respectively. PVT/HNPCM, enhanced 31.46% 28.70% respectively conventional in study. With cooling-water mass flow rate 0.0021 kg/s, highest 47% achieved system, whereas 51.28% PVT/HNPCM system. analysis variance test yielded P value <0.0001 which less than 0.05 overall indicating suggested model's appropriateness statistical significance. These optimal conditions are observed when solar intensity ranges from 774 W/m2 809 0.002 kg/s both systems. However, these advance sustainable urban development climate goals combining panels' generation energy harvesting, boosting built environment.

The buildings sector consumes a significant amount of raw materials and energy resources, with high-energy consumption environmental impact. To achieve net-zero emissions, it is crucial to address the substantial carbon footprint generated by in operation. A promising solution lies development renewable sustainable building capable efficiently storing thermal regulate indoor temperature without relying on operational (HVAC systems). Here we report wood-phase change material (PCM) composite, referred as PCM-wood, which holds potential for energy-efficient buildings. composite shows excellent regulation capability melting enthalpy 113 J g−1 at 22 °C solidification 114 21 °C. Despite some loss mass melting, PCM-wood showcases stable performance over 50 heating/cooling cycles wood modification does not negatively impact tensile strength material. Hence, combines structural efficient storage ability passively temperature, buffering fluctuations more than 6 Such passive strategy has significantly reduce help reducing mitigating CO2 emissions.
