Phase change photovoltaic thermal management device

A phase change photovoltaic thermal management device, comprising:

• a photovoltaic panel configured to convert solar radiation to electric power;
• a phase change material layer attached to a back side of the photovoltaic panel;
• wherein the phase change material layer is a continuous layer directly adjacent to the back side of the photovoltaic panel;
• wherein the photovoltaic panel is removably attached to the thermal management device via the phase change material layer:
• wherein a phase change material of the phase change material layer comprises polyethylene glycol (PEG) and magnesium doped calcium carbonate (MgCaCO3), and wherein magnesium is present in the MgCaCO3 at a concentration of 5 to 15 mole percent (mol %) based on the total moles of the MgCaCO3;
• a Seebeck thermoelectric generator having a first surface attached to the phase change material layer;
• a heat sink attached to a second surface of the Seebeck thermoelectric generator, wherein the heat sink is configured with a sinuous coil, a water inlet port and a water outlet port connected to the sinuous coil, a fan, an exit port and a plurality of heat fins;
• a casing box configured to enclose a back and sides of an assembly of the photovoltaic panel, the phase change material layer, the Seebeck thermoelectric generator and the heat sink;
• and
• a glass cover configured to cover a top surface of the photovoltaic panel, wherein the glass cover is attached to the casing box.
