Abstract

This study considers the potential of application of graphene-based nanofluids as heat-transfer agents in direct absorption solar collectors. It has been revealed that graphene-based nanofluids have superior absorption ability when interacting with monochromatic (520 nm) and near-IR radiation. As compared with distilled water, the use of graphene-based nanofluids as working fluids in direct absorption solar collectors increases their efficiency even at very low concentrations of dispersed phase particles. However, in order to apply graphene-based nanofluids as working fluids in energy systems, some issues need to be solved, primarily those related to their low stability and thermal instability.
