Background: Energy is an indispensable part of human life. To meet the ever-increasing energy demands and mitigation of its adverse production effects, the new technological advancements and shifting towards the renewable energy resources (RERs) has become imminent. Solar energy is the most prominent among RERs, where solar thermal collectors utilizes more effective working wavelength range compared to photovoltaic cells. Nanofluids are engineered working fluids for enhancing collector performance. Synthesized carbon nanofluids usually have higher thermal conductivities than metals and metal oxides, leading to higher collector performance. Methods: This review presents the outcomes of experimental investigations conducted with carbon based nanofluids in non-concentrating collectors and discusses its effects on thermophysical properties. Findings: From review, it can be inferred that the carbonaceous nanofluids improved the performance of solar collector systems. It was noted that the thermal performance and stability of nanofluid was affected by several factors such as preparation method, working temperature, concentration and dimension of nanoparticles etc. Likewise, the performance enhancements of collectors reported were mutually inconsistent and repeatability of the data was difficult to produce. There are also lack of studies on stability of nanofluids after utilization, carbon allotropes except nanotubes and graphene, and base fluids except water and glycols.
