摘要

光伏(PV)电池板可利用光伏效应将太阳光转化为电能。光伏电池板过热会限制太阳能的性能,而创新的双面电池板技术会更好地积聚热量,从而导致寿命缩短和成本增加。本研究的重点是通过采用多孔介质和纳米流体来限制光伏板的温度,这也有助于提高太阳能集热器系统的热效率。通过超声波法将氧化铝(Al2O3)和二氧化硅(SiO2)纳米颗粒分散在体积分数为 0.5% 的水中,多孔介质由碳化硅材料制成。此外,还引入了 Al2O3 和 SiO2 的混合物,以研究纳米流体和多孔介质在光伏板冷却中的组合效果。基于实验,计算了热增益、电功率、光伏总功率、热效率、电效率和放能效率。混合纳米流体的峰值流体温度、热增益、电功率和总功率分别约为 72.4 ℃、534.2 W、221.4 W 和 258.6 W。此外,多孔介质混合纳米流体的平均热效率、电效率和能效分别约为 59.8%、8.8% 和 7.1%。因此,与其他流体条件相比,纳米流体与多孔介质的混合集成显示出峰值光伏性能和更高的热效率和电效率。

Hybrid photovoltaic solar system performance enriched by adaptation of silicon carbide made porous medium

Hybrid photovoltaic solar system performance enriched by adaptation of silicon carbide made porous medium

Photovoltaic (PV) panels are prospective for sunlight to direct electrical energy using the photovoltaic effect. Overheating of PV panels is influenced to limiting the solar performance, and innovative bifacial panel technique found better heat build-up leads to reduced lifespan and costlier reasons. The present research focuses on limiting the PV panel temperature by the implementation of the porous medium and nanofluid, which also assists in enhancing the thermal efficiency of the solar collector system. The alumina (Al2O3) and silicon dioxide (SiO2) nanoparticles were dispersed within the water with a volume fraction of 0.5% through the ultrasonication method, and the porous medium was made of silicon carbide material. Furthermore, the hybrid of both Al2O3 and SiO2 was introduced to study the effect of combined nanofluids and porous medium in PV panel cooling. Based on experimentation, heat gain, electrical power, total power by PV, thermal efficiency, electrical efficiency, and exergy efficiency were calculated. The peak fluid temperature, heat gain, electrical power, and total power by hybrid nanofluid are about 72.4 °C, 534.2 W, 221.4 W, and 258.6 W, respectively. Furthermore, the average thermal, electrical, and exergy efficiency is about 59.8%, 8.8%, and 7.1% by hybrid nanofluid with porous medium. Hence, the hybrid nanofluid and porous medium integration shows peak PV performance and higher thermal and electrical efficiency than other fluid conditions.
