A comprehensive review of the influence of nanomaterials on the thermal performance of a solar thermal collectors

The present review article investigates the utilisation of nanomaterials with the aim of augmenting the thermal efficiency of solar thermal collectors (STCs). A comprehensive analysis is conducted on the STC through the utilisation of nanomaterials, leading to an improvement in its performance. This evaluation highlights the similarities in the results through an in-depth discussion on several types of criteria that might impact the performance of STCs. In order to justify and, finally, explain the behaviour of nanomaterials for the purpose of thermal augmentation of STCs, analysis was carried out and is being discussed here. This review article presents a novel aspect that is based on an extensive investigation that was based on a significant amount of research that had been published in the past. The study indicated that the use of nanomaterials may boost the heat-absorbing ability of the STCs.
