Abstract In this work, the thermoelectric generator (TEG) layer has been combined with conventional layers of photovoltaic-thermal (PVT) modules to use waste heat and increase efficiency. To reduce cell temperature, there exists a cooling duct in bottom PVT-TEG unit. Type fluid within structure can change performance system. So, hybrid nanofluid (mixture Fe 3 O 4 MWCNT water) replaced instead pure water three various configurations cross section [STR1 (circular), STR2 (rhombus), STR3 (elliptic)] have implemented. Through tube incompressible laminar flow solved while solid panel, conduction equation simulated involving sources resulting from optical analysis. According simulations, third (elliptic) best rise inlet velocity causes overall enhance about 6.29%. The values thermal electrical performances for elliptic design equal fractions nanoparticles are 14.56% 55.42%, respectively. With design, efficiency improves 16.2% comparison an uncooled
