A new composite heat transfer fluid consisting of tetralin and fullerene has been proposed for photovoltaic thermal hybrid solar harvesting. It features a unique absorption spectrum that is capable sharply cutting off energy irradiated in the range wavelength from 300 to 650 nm, making it perfect candidate simultaneous harvesting both components energy. The revealed outstanding stability facile synthesize root, which are two main obstacles applicability nanofluids. was shown experimentally additives do not alter significantly it’s thermophysical properties apart viscosity increases moderately. Besides, tetralin/fullerene solutions show similar thermohydraulics performance pure laminar flow regime or insignificantly lower transient turbulent regimes. figure merit analyze consider only exergy losses due kinetic dissipation, but also associated with finite temperature difference exchanger. As result, indicates decrease directly proportional concentration. performed simulation suggests total efficiency flat-plate photovoltaic/thermal collector goes up 60.4 % estimated according regulation (EU) No. 811/2013. Finally, life cycle analysis further improvement root view environmental impact.
