Current research focuses on employing MXene/ethanol nanofluid (NF) as a working fluid in an array of two-phase closed thermosyphons (TPCT) for cooling the PV panel of hybrid solar photovoltaic/thermal (PV/T) system from the rear. Unique features such as high electrical conductivity, capacitive capacity, and hydrophilicity were the advantages of MXene nanoparticles. Moreover, comparisons between PV systems are provided in terms of performance and efficiency parameters. The results revealed that the optimum inclination angle for the panels was identified as 30°, and the optimum filling ratio was determined as 50 %. Applying NFs up to an optimal concentration of 1 % instead of the base fluid increased the temperature drop behind the panel, improved the panel output power, and enhanced overall efficiency. A temperature drop of 19.21 °C and an increase in electrical output of 1.62 W were observed behind the module at a 1 wt% MXene concentration. Therefore, the presented study discloses very high performance in PV/T systems.

研究 MXene/乙醇纳米流体对混合光伏/热 (PV/T) 面板热虹吸冷却的影响

目前的研究重点是采用 MXene/乙醇纳米流体 (NF) 作为两相封闭热虹吸管 (TPCT) 阵列中的工作流体，从后部冷却混合太阳能光伏/热 (PV/T) 系统的光伏电池板。 MXene 纳米颗粒的优点是具有高导电性、电容性和亲水性等独特特性。此外，还提供了光伏系统之间性能和效率参数的比较。结果表明，面板的最佳倾斜角度确定为30°，最佳填充率确定为50%。使用最佳浓度为 1% 的 NF 代替基础液可增加面板后面的温降，提高面板输出功率并提高整体效率。在 1 wt% MXene 浓度下，模块后面的温度下降了 19.21 °C，电输出增加了 1.62 W。因此，本研究揭示了 PV/T 系统的非常高的性能。
