Summary of the research project: Among technologies of energy harvesting, thermoelectricity has unquestionable advantages related to its simplicity, its reliability and the absence of any moving parts and any pollution through greenhouse gas emission. These advantages are the consequence of an entirely solid state technology which converts any source of heat directly into electricity. All these favourable characteristics place the thermoelectric converters as potential candidates to provide to the connected objects of tomorrow the small quantities of energy necessary to their operation or to maintain the charge of the battery. The subject of this thesis aims at studying the conversion potential of thermoelectric generators and to predict their electrical performance. This exploratory study will be conducted using digital tools. The influence of many factors (temperature of hot and cold sides, properties of the materials, design of the generator, thermal coupling,…) on the electrical power output and on the thermomechanical properties will be examined in detail.

Type of funding: EnSO and Tours 2015
Name of Director: Frédéric Sabary, Tiberiu Minea
Dates of the position: 12/11/2014-05/06/2018
Summary of the research project: The research project aims at modelizing RF plasma under nitrogen atmosphere and interaction with surface of the substrate. This modelisation is very important to fully understand LiPON deposition mechanism with a rf sputtering process. LiPON is crucial in terms of battery performances (Internal resistance) and yield. Spatial repartition of flux of particules (ions, electrons, atoms) is studied in order to better understand growth of LiPON layer during sputtering. Different models from 0D to 2D are studied.

Position 6 - University of Liège

Name of the PhD student: Korina HARTMAN
Type of funding: EnSO/FRIA
Industrial Partner: PRAYON
Name of Directors: Benoît Heinrichs

Dates of the position: 1/10/2016 – (30/9/2020)
Summary of the research project: Development of a wet coated electrolyte for microbatteries
The goal of the thesis is to synthesize a solid-state electrolyte for lithium-ion microbatteries. This solid electrolyte should be able to mechanically hinder the growth of lithium dendrites at the anode. An ionic liquid-based electrolyte solution will be confined within a silica matrix obtained by a sol-gel process as an inorganic host material. Ionic liquids (IL) display negligible vapour pressure and wide chemical, electrochemical, and thermal stability. ILs can be immobilized in a 3 dimensional organic or inorganic network while trying to keep their properties. Silica-based matrix obtained by a sol-gel process will be focused as inorganic host material. This two-phase system is called an ionogel.

 

Position 7 - University of Liège

Name of the PhD student: Chellda Exantus

Name of Directors: Nathalie Job
Dates of the position: 1/10/2016 – (30/9/2020)
Summary of the research project: Study of the seed of ZnO nanowire and its effect on ZnO NW growth
One-dimensional Zinc Oxide Nanowires (ZnO NWs) have attracted a lot of attention due to their remarkable physical and chemical properties for electronic and optical devices such as chemical sensors, field effect transistors, and nanogenerators. Piezoelectric materials like zinc oxide exhibit an induced voltage under applied stress. This piezoelectric property has interesting applications in energy harvesting systems, like autonomous micro-devices.
At the moment, the synthesis of well-aligned nanowires from precursor liquid solutions (i.e. via wet chemistry), without crystalline defects, is difficult. Therefore a combined process (coating of a substrate using a sol-gel process, i.e. seed deposition, followed by growth of ZnO nanowires using wet chemistry) is under development at the University of Liège and has to be improved for real exploitation. The final process needs to be suitable for large-scale manufacturing (i.e. 20 nm/min growth speed), and provide a micrometric layer of well-aligned nanowires with good crystallinity. Several seed deposition techniques using sol-gel chemistry will be studied to improve the quality of the nanowires. In order to guarantee sufficient growth speed, a kinetic study will be performed, taking into account the control of the synthesis and deposition process variables, as well as constraints related to the manufacture of nanogenerators. The characterization of both the seed layer and the deposited nanowires will be done by scanning electron microscopy, atomic force microscopy, photoluminescence, profilometry and X-ray diffraction. The obtained layers will then be assembled as nanogenerator and characterized using a piezoelectric test-bench. The goal is to reach a power of 1 μW/cm³. After optimization of the combined process, the seed deposition technique and the nanowire growth method will be scaled up (pilot scale).

 

Position 8 - University of Liège

Name of the PhD student: Carlos PAEZ
Type of funding: EnSO/EnSOWal
Industrial Partner: PRAYON
Name of Directors: Benoît Heinrichs
Dates of the position: 1/08/2016 – (30/6/2021)

Summary of the research project: Development of doped LiCoO2 wet coated cathodic thin film for microbatteries
The thesis project consists mainly in the design, synthesis and shaping of a new generation of Lithium-ion micro-batteries via the sol-gel process or by colloidal liquid process. The main challenge is to replace the current Physical Vapor Deposition (PVD) technologies used today in the microelectronics industry despite their high cost and complexity. The colloidal liquid or sol-gel technology offers a wide range of deposition possibilities for film formation in simple, clean (environmentally friendly), economical and industrially exploitable processes

 

Position 9 - CNM-CSIC

Name of the PhD student: Marcos DUQUE
Type of funding: EnSO
Name of Directors: Gonzalo Murillo Rodriguez, Jaume Esteve Tinto
Dates of the position: 01/10/2017 - (01/06/2021)
Summary of the research project: The research project is focused on two branches. The first branch is the modelling, design and fabrication of piezoelectric devices for energy harvesting using the combination of microfabrication technologies and Inkjet printing for the integration of piezoelectric nanostructures and MEMS. The second is the schematic level design and layout of a converter circuit for harvesting energy with MEMS piezoelectric devices. The main aim of this circuit is to condition and raise the voltage of the signal generated by a piezoelectric MEMS device, in conditions in which the piezoelectric generator is not able to reach to 1.8 V - 3.3 V or power supply the wireless sensor node.
