摘要

In this work, a novel conceptual water-based hybrid photovoltaic thermal collector design was modeled and numerically simulated using ANSYS Fluent software. The novelty concerns to superimpose a layer of water to the PV module; it will serve to cool the PV cells and also to filter the incoming solar radiation. Water as a natural filter will absorb IR radiations, therefore, it collects thermal energy, besides, it will let the visible radiation pass, reach the PV and generates electricity. Based on the first and second laws of thermodynamics, an analysis of the overall efficiency of the novel hybrid water-based-PVT is performed. The simulations concern the impacts of intrinsic parameters (the height of the cooling channel and water inlet velocity) and extrinsic parameters (the wind velocity, solar irradiation, and the ambient temperature) on the overall energetic and exergetic performances of the PVT. The results show that in terms of energy quantity and quality, the new proposed PVT is superior to previously proposed ones. In addition, a new method to determine the optimal height of the rectangular channel is also proposed and validated.
