dc.description.abstractIn this study, the effect of the fin surface on the electrical performance of passively cooled photovoltaics (PV) modules equipped with flat (PVf) and tread (PVt) surface finned heat sinks was experimentally investigated. PVf and PVt modules were fabricated with heat sinks by filling phase change material (paraffin)/aluminum chip mixture between the PV module and heat sink. The mean ambient temperature, solar radiation, and solar power during the experiment were about 13°C, 864 W/m2, and 247, respectively. The electrical power of the PVf and PVt modules was increased by 10.84% and 17.2%, respectively, while the average temperature was decreased by 11.78% and 16.5%, respectively, compared to the PV module. The PVt module provided 5.37% more effective cooling and a 5.74% higher electrical power than the PVf module. The electrical efficiency of the PV module was 11.35%, and the rate of increase was 1.21% and 1.95% for the PVf and PVt modules via cooling. Compared to the PV module, the electrical exergy of the PVf and PVt modules increased by 10.84% and 17.2%, respectively, at an average solar exergy of 230.61 W, while their thermal exergy decreased by 23.64% and 32.3%, respectively. Compared to the PVf module, the thermal exergy of the PVt module was reduced by 11.34%, and the electrical exergy was increased by 5.74%. The increase in exergy efficiency is 3.14% and 4.51% for PVf and PVt modules versus the PV module. © 2022 American Society of Civil Engineers.en_US
