Effective and efficient utilization of solar energy is highly demanded in the energy industry. Herein, based on the excellent optical properties of MXene, an MXene enhanced therminol®VP-1 nanofluid is proposed for direct absorption solar collector to efficiently absorb solar radiation. The nanofluid is experimentally prepared and characterized. Subsequently, the influence of mass fraction of MXene, collector height, and working temperature on the collecting efficiency of the nanofluid in DASCs is numerically investigated. The results show that even with a low mass loading such as 50 ppm, MXene enhanced therminol®VP-1 nanofluid still can effectively absorbs solar spectrum. The intercept efficiency of 50ppm nanofluid is 83.32%, which is higher by 20.48% than that of therminol®VP-1. The efficiency is strongly affected by collector height and MXene content and first increases and then decreases with increasing the mass loading of MXene. Moreover, the best content of MXene gradually decreases with the increase of the collector height. These findings suggest that MXene enhanced therminol®VP-1 nanofluid has promising prospects to achieve efficient solar photothermal conversion.
