 Collector&description=A photovoltaic/thermal (PV/T) collector is a combination of photovoltaic cells with a solar thermal collector, through photovoltaic and photothermal interaction, generating solar electricity and solar heat simultaneously. Hybrid PV/T collector has aroused widely range of attention among researchers in the last decade, but so far rare analysis of the fluid mass flux that affect the overall performance has been attempted, and less exergetic balance analysis for a hybrid PV/T has been reported. The effect of fluid mass flux on thermal and electrical performance for a hybrid PV/T collector was tackled in this paper from the point view of the first and second law of thermodynamics. By the given design and operation parameters used for the present study, taking materials consumption, economical and heat transfer performance into consideration, NTU (Number of Transfer Units) for hybrid collector should be optimized to the value of 0.5, and the hybrid PV/T collector operates at optimum mass flux (0.002kg/s•m<sup>2</sup>) not only can improve the electrical and thermal efficiency, but also can assure the quality of the output energy.&picture=http://www.aascit.org/aascit/decorators/img/journal/925.jpg)
