Abstract

This study synthesized three form-stable eutectic phase change materials (FS-EPCMs) with varying docosane/coconut oil ratios (30/70, 50/50, and 70/30) to achieve different melting points and latent heats. To improve thermal conductivity, layer-by-layer synthesized ZnO/MnO₂ nanoparticles were incorporated into the FS-EPCMs. Response surface methodology (RSM) optimized PV panel temperature and electrical efficiency, with the coconut oil volume fraction, FS-EPCM thickness, and ZnO/MnO₂ weight fraction identified as significant factors (low p-values). ANOVA revealed key interactions influencing electrical efficiency, with high F-values (212.70 for temperature, 185.05 for efficiency) and low p-values (<0.0001) demonstrating model significance. High R² values (0.9974 for temperature, 0.9970 for efficiency) and adjusted R² values (0.9927, 0.9916) indicate strong model fit, further supported by "Adequate Accuracy" scores (49.87, 44.14). Incorporating ZnO/MnO₂ nanoparticles significantly enhanced PV panel cooling. Optimal performance was achieved with a FS-EPCM suspension comprising 45.30 % coconut oil, 55.70 % docosane, and 16.64 % wt ZnO/MnO₂ nanoparticles at a thickness of 2.477 cm, resulting in a panel temperature of 48.51 °C and an electrical efficiency of 13.11 %.

形态稳定相变材料与导电ZnO/MnO2纳米颗粒集成光伏板的性能表征、实验研究与优化

本研究合成了三种形式稳定的共晶相变材料（FS-EPCMs），它们具有不同的docosane/coconut oil比例（30/70,50/50和70/30），以获得不同的熔点和潜热。为了提高热导率，将合成的ZnO/MnO2纳米颗粒逐层掺入FS-EPCMs中。响应面法（RSM）优化了PV板的温度和电效率，其中椰子油体积分数、FS-EPCM厚度和ZnO/MnO2重量分数被认为是显著因素（低p值）。方差分析揭示了影响电效率的关键相互作用，高f值（温度为212.70，效率为185.05）和低p值（<0.0001）表明模型显著性。较高的R2值（温度为0.9974，效率为0.9970）和调整后的R2值（0.9927,0.9916）表明模型拟合较好，“足够的准确性”得分（49.87,44.14）进一步支持了模型拟合。ZnO/MnO2纳米颗粒的加入显著提高了光伏板的冷却效果。当FS-EPCM悬浮液中含有45.30%的椰子油、55.70%的docosane和16.64% wt的ZnO/MnO2纳米颗粒，厚度为2.477 cm时，获得了最佳性能，导致面板温度为48.51°C，电效率为13.11%。
