Broadband absorbing mono, blended and hybrid nanofluids for direct absorption solar collector: a comprehensive review

Abstract The evolution of nanofluids over the years has opened new research opportunities in field renewable energy. Research on optical properties for application direct absorption solar collectors (DASCs) is progressing at a burgeoning speed. In DASC system, nanofluid with high absorptivity can convert incident energy into thermal fluid. dispersed nanoparticles fluid act process through phenomenon and scattering. Studies conducted property characterization monocomponent have become saturated. Moreover, photothermal efficiency (PTE) be enhanced by using multicomponent nanofluids. Nanofluids prepared varying materials, shapes sizes tune spectra bulk to improve PTE. A hybrid nanocomposite similarly enhance due synergy materials present particle. this review, comprehensive survey synthesis different monocomponent, blended been performed.
