Item Experiment-based Methodology of Kinetic Battery Modeling for Energy Storage(Research Gate, 2018-08) Bako, Zeinabou Nouhou; Tankari, Mahamadou Abdou; Lefebvre, Gilles; Maiga, Amadou SeidouThis paper presents a methodology of the battery modeling based on experimental tests results. As main contribution, authors conducted an analysis of the main constraints and effects of each parameter of the batteries model on its behavior and lifetime. This can help to improve the accuracy of the model. Due to its capability to model the recovery effect and the rate-capacity one, the Kinetic Battery Model serves as basis of the study. Results of experimental tests are used to realize the analysis and to define the suitable methodology of batteries parameters identification. These last can serve for prediction and estimation of the battery lifetime according to the actual operating conditions, particularly in microgrid and distributed systems.Item Morphological and Optoelectrical Characterization of Silicon Nanostructures for Photovoltaic Applications(Research Gate, 2019-02-07) Dieng, Babacar; Toure, Moussa; Beye, Modou; Kobor, Diouma; Maiga, Amadou SeidouMetal (silver)-Assisted Chemical Etching (MACE) method is used to fabricate silicon nanostructures like silicon nanowires (SiNWs) and silicon nanocones (SiNCs). The morphological characterization of fabricated SiNWs has shown that 5 minutes is the optimal time of silver deposition on silicon substrate. Silicon nanocones (SiNCs) were also fabricated by etching vertical SiNWs with a AgNO3/HF/H2O2 solution. The optical and electrical properties of SiNWs and SiNCs are analyzed and compared with those of the bulk silicon. The fabricated SiNWs (SiNCs) reduce the surface reflectance and the sheet resistance down to 6% (3%) and 9.143 Ω/sq (6.997 Ω/sq) respectively.
