1. A hybrid photovoltaic thermal (PVT) system, comprising:
a photovoltaic (PV) panel;
an optical filtration (OF) channel located above the PV panel, wherein the OF channel contains an OF fluid configured to transmit a first spectrum of solar radiation that is within a predefined spectral range and absorb a remaining, second spectrum of the solar radiation that is outside the predefined spectral range;
wherein the OF fluid contains water which contains nanoparticles selected from the group consisting of platinum nanoparticles and a combination of gold nanospheres and nanorods and indium tin oxide (ITO) nanocrystals,
a cooling fluid (CF) channel located below the PV panel, wherein the CF channel contains a cooling fluid,
wherein the cooling fluid is one of polypropylene glycol and polydimethyl siloxane based oil which contains nanoparticles suspended in the cooling fluid, wherein the nanoparticles in the cooling fluid are selected from the group consisting of indium tin oxide and gold nanospheres; and
a phase change material (PCM) layer inserted between the PV panel and the CF channel, wherein the PCM layer contains graphene nanoplatelets in a concentration greater than or equal to 10 wt. % of the total weight of the PCM layer.
