Researchers from Irans Babol Noshirvani University of Technology have investigated the enhancement of PV panel electrical efficiency by simulating a concentrating PV CPV system that integrates parabolic reflectors, a paraffin-based nanomaterials cooling system aimed at reducing solar module temperature, and a thermoelectric generator TEG that turns the excess thermal energy into electrical energy. To simulate the heat flux introduced by the reflectors, SolTrace software was employed, while the unsteady, three-dimensional thermal behavior of the system was analyzed using Ansys Fluent, the researchers explained. The innovation of the current article lies in the combined use of SolTrace for precise reflector modeling, heat flux variation analysis across PV layers, and the layered structures response to dust accumulation. A few cases were teste stanley cup d in the simulation program; the first, for reference, included only the CPV panel. In the s stanley cup econd case, a cooling system has been implemented under the panel using a container filled with paraffin RT35HC enhanced with single-walled carbon nanotube SWCNT nanoparticles. In th stanley cup e third case, the container also included an array of fins to promote conductive heat dissipation across the PV panel surface.All of those three cases were then tested under clean conditions as well as under dust deposition. Later on, all versions of the system were also equipped with a TEG. TEGs can convert heat into electricity through the Seebeck effect, wh |
